Safari:  Safari is the default web browser that comes with your Mac OS X designed by Apple based on the Apple’s WebKit engine. It was first released in 2003 with Mac OS X 10.3 – Panther, then a mobile version was included in iOS devices since the introduction of the iPhone in 2007. A Windows version of Safari was also released in the year 2007 , which Apple discontinued in 2012. The first version of Safari for Mac was named Safari 1 and now the current version as of writing is Safari 12.0.2 , released for macOS 10.14 Mojave . It got some new features like Favicon or website icons in tabs and more. For more information, read What’s new in macOS Mojave . Apple claims that the new version of Safari is more secure and reliable but as we know that nothing is perfect in this world. Just like other browsers, Safari also gets infected with Malware, Spyware or Adware. Sometimes new updates from Apple are rolled out which makes Safari unstable or even remove it from the system. In order to deal with such situations you should know how to reinstall safari .

Here in this article, I would be explaining to you about some major issues with Safari along with their solutions and if none of the solutions works, the last resort to you is reinstall Safari which I have covered in the end.

Issue / Error With Safari

Safari was recently in hot search trends due to Apple’s latest software updates to the Safari web browser issued on 3rd December, 2015 which reportedly failed and removed Safari from users’ systems. There was another update to Safari which made it incompatible with the OS and changed the safari logo to a crossed out circle. If you would try to open Safari it would show an error message that reads “The version of safari installed on this Mac is not compatible with the current version of OS” . You may also get one of the following error messages.

• “This version of Safari is no longer supported. Please upgrade to a supported browser.”
• Safari crashes as soon as you open it and shows error message Safari quits unexpectedly.
• Can’t connect to the server
• Safari loads partial webpage”
• Safari may become corrupt and may not run at all or runs very slow like a snail, it takes ages to open a web-page, while other browsers run perfectly fine. So if it is not working or having problems to browse websites, you may need to reinstall it.

As per the Apple there is no way to reinstall Safari except reinstalling OS X. Reinstalling OS X does not delete any user’s files, however, its a lengthy process and require so much time and care. But before we reinstall the OS X, I would suggest you to try the following troubleshooting which may fix the issue with Safari. We could also install Safari as a standalone app using a third party software called Pacifist , which is explained in the end.

Troubleshooting the issues with Safari

#1. check to see if safari is running in 32 bit mode..

Apple introduced 64-bit version of Safari with the release of Snow Leopard (OS X 10.6), but it was still possible to run Safari in 32-bit mode for backward compatibility. At the time of release so many JavaScript application and Safari extensions were not designed for 64 bit version of Safari so users had to run Safari in 32-bit mode. After Mountain Lion( OS X 10.8) , Apple removed option to change the bit mode of Safari as all of the extensions and JavaScript Applications were already upgraded to run in 64 bit mode.

Check if Safari is running in 32 bit mode

Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to:  Open in 32 bit mode is Checked, Uncheck it, quit then relaunch Safari.

2. Reinstall Flash Player Plug-ins.

Safari has a long term issue with Flash Player which was also published in an article written by Steve Jobs- Thoughts on Flash . Check safari by Uninstalling flash Player . After the safari is uninstalled delete its left over files from the following locations if available.

3. Restart your computer.

4. reinstall and enable flash player for safari..

Install Flash Player directly from Adobe . If you are having trouble with web installer, download the standalone Flash Player version for Safari and Firefox – NPAPI directly from https://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_osx.dmg

5. Remove incompatible Flash Extension

Remove ClickToFlash extension if it is installed, it can prevent Flash based videos from streaming. It can be found as a plugin in /Library/Internet-Plug-Ins .

6. Make sure the JavaScript and plugins are allowed in Security settings of Safari Preferences window.

Also check the Safari Develop Menu to make sure “ Disable JavaScript ” is not checked. Learn how to enable Develop Menu in Safari .

7. Check Safari after Turning Off the IPv6 Support.

On February 4, 2008 , IANA adds AAAA records for the IPv6 addresses of six root name servers. With this transition, it became possible to resolve domain names using only IPv6.

On August 28, 2009 , OS X 10.6 Snow Leopard  was released to manufacturing worldwide and reported to have issues with safari if using IPv6.

On June 6, 2012, the Internet Society together with many other big companies and organizations held World IPv6 Launch Day, a global permanent deployment of IPv6.

On July 25, 2012, Mountain Lion- OS X 10.8 was released and had a known issue with ipv6 and dns implementation and people started using Chrome and firefox until Apple admitted there was a bug and fixed it. The Same bug chased OS X 10.10 Yosemite too.

To fix this issue, first make sure your Mac is up to date by installing all Software updates. If its already updated and you still have the same issue then turn off the IPv6 as mentioned below.

For OS 10.6.8 and earlier

a.) Go to System Preferences > Network > Advanced > TCP/IP > Configure IPv6: Off. Click “OK” then Apply and then test after restarting the Mac. You could also use the following command in terminal to do the same.

Turning off IPv6 support for ethernet: networksetup -setv6off Ethernet

Disabling IPv6 for wireless: networksetup -setv6off Wi-Fi

Note: Disabling IPv6 may also stop you from using some of the core OS X system services, like the discovery service Bonjour, AirDrop, because they use IPv6. Accordingly, disabling IPv6 may render AirDrop sharing unusable, certain print services configured on Bonjour will become unavailable, and some other convenient Mac features may turn inoperable as well.

For OS X 10.7 and above

b.) Go to  System Preferences > Network > Advanced > TCP/IP > Configure IPv6: Link-local only. Click “OK” then “Apply” and then close preferences. Check Safari after Logout and log back in, it should be working fine.

Re-Enabling IPv6 for Wi-Fi & Ethernet in OS X

Of course, reversing the above change is also possible, and you can re-enable IPV6 support with the following command strings entered into the terminal:

For Wireless Interface networksetup -setv6automatic Wi-Fi

For Ethernet Interface networksetup -setv6automatic Ethernet

8. Flush the DNS Cache

OS X keeps a local cache of resolved DNS queries for a time defined by the DNS server. Sometimes it might be necessary to reset the cache immediately and re-query a DNS server if an entry on your DNS server has recently changed. To Flush (Reset) DNS Cache, use the terminal commands below for the version of OS X you’re using.

OS X Yosemite and later

Use the following Terminal command to reset the DNS cache in OS X v10.10.4 or later: sudo killall -HUP mDNSResponder Use the following Terminal command to reset the DNS cache in OS X v10.10 through v10.10.3: sudo discoveryutil mdnsflushcache

OS X Mavericks, Mountain Lion, and Lion

Use the following Terminal command to reset the DNS cache in OS X v10.9.5 and earlier: sudo killall -HUP mDNSResponder

Mac OS X Snow Leopard

Use the following Terminal command to reset the DNS cache in OS X v10.6 through v10.6.8: sudo dscacheutil -flushcache

9. Try Open DNS

For, “can’t connect to server” issues, Apple suggests using Open DNS or Google DNS. If you are using Safari 5.0.1 or later and you are facing issues like Slow or partial webpage loading, or webpage cannot be found. Try open DNS server mentioned below. Open System Preferences > Network > Advanced > DNS Click + and type: 208.67.222.222 Click + again and type. 208.67.220.220 Click ‘ OK’ . Quit and relaunch Safari to test.

If that didn’t help, go back to the DNS tab. Select the 208 addresses then click ➖ under the DNS Servers panel to delete. Then click + to add Googles’ DNS Server. 8.8.8.8 8.8.4.4 Then click OK and try Safari.

10. Scan the Computer with Malwarebyte Anti-malware

Your Safari might be infected with Malware, Spyware or adware which is causing Safari to crash. I have created a list of Common Malware and Adware , check to see if your Computer is infected with any of these.Scan your computer with Malwarebyte -Anti-malware for Mac . Remove all the found items as they are harmful to your computer.

Look into the following folders and browse their contents for any third-party add-on files. Move the third party add-on files to trash.

11. Reset Safari

If all the above methods have been tried and Safari still does not work. Reset the Safari by deleting the following files.

Delete Keychain entry named “ Safari Extensions list ” from Keychain Access located in /Application/Utilities folder.

Clear the NVRAM variables by typing the following command at terminal. sudo nvram -c

Why will you have to Reinstall Safari ?

If all the above mentioned steps have been exhausted and safari still doesn’t seem to be working then it might be a possibility that “Safari.app” application file has become corrupted. And the final resort to you is either clean reinstall Safari or Reinstall the OS X.

How would you Uninstall Safari?

Uninstalling Safari from Mac is not as easy as uninstalling any third party apps. To uninstall safari you must either reinstall the operating system or use a third party app to uninstall the application for you and again to reinstall Safari, you either reinstall the whole Operating system or use a third party software to extract it from OS X installation file.If you normally try to move safari to trash you will see following error message. “Safari can’t be modified or deleted because it’s required by OS X.”

Follow the below mentioned steps to uninstall Safari.

1. uninstall safari using terminal command.

Launch the Terminal, located in / Applications/Utilities/ folder. Type the following command and hit enter to change the current working directory(CWD) to the Applications directory. cd /Applications/

Now that you are in the Applications folder, you can start deleting apps. You will not get a confirmation of the removal, the app will simply be uninstalled completely. The following commands will only work when used in the /Applications/ directory.

sudo rm -rf Safari.app/

2. Uninstall Safari manually.

Go to the /Applications folder and Right-Click or Control-click on Safari icon and select Show Package Contents.

This will open a new folder called contents and it will have other bundled software and info.plist files inside it. Simply select all the package contents and delete them to uninstall safari.

After deleting the package contents you also need to delete other supporting configuration and preferences file for Safari exactly as mentioned above in Step 11-Reset Safari . Restart the computer now and Safari is uninstalled completely.

3. Uninstall Safari using a Third party App.

CleanMyMac 3 is a free application that can be used to uninstall Safari on macOS. In OS X El Captian, you cannot remove Safari with CleanMyMac 3 and will run into this message: “Safari.app” couldn’t be removed because you don’t have permission to access it.”

Reinstall Safari on my Mac

How would you reinstall safari.

There are multiple ways of reinstalling Safari. If your OS X version has got a new Combo update released and you haven’t installed it, Look into the details of Combo update and see if it contains Safari. If it has Safari then installing the Combo will bring Safari back as a fresh new updated version. If your OS X is already updated then follow one of the steps below.

#1. Safari can also be downloaded from Softpedia and reinstalled – http://mac.softpedia.com/get/Internet-Utilities/Safari.shtml

Download it from the Softpedia and reinstall it as usual.

#2. Use Pacifist to extract Safari out of the original OS X installation file.

Pacifist is a shareware application that can extract the contents from Mac OS X .pkg package files, .dmg disk images , and .zip, .tar, .tar.gz, .tar.bz2, and .xar archives. This is specially used when a native OS X application becomes damaged and needs to be reinstalled without the hassle of reinstalling all of Mac OS X.

Pacifist is compatible with Mac OS X 10.8 or higher, including Mac OS X 10.11 “El Capitan”. Pacifist requires a 64-bit Intel™ processor.

Download the latest version of Pacifist in zip or disk image format. For users using versions of Mac OS X older than 10.8, download older versions of Pacifist here . Now to Reinstall Safari you need the source image to extract safari from.

You can extract Safari from the following sources.

• Original OS X installer dmg file.
• Hidden Recovery Partition on any Mac.

A.) Extract Safari from original OS X installer DMG file.

90% of the times your Mac keeps a copy of the complete OS X installer that you downloaded to upgrade your system. This download is by default saved in /Application folder. Go to the /Application folder and see if you have OS X El Capitan or the current running version of OS X on your Mac, usually named as “ Install macOS Sierra.app “. if you do not see it in Application folder, download it from the App store.

1. Open Pacifist and select the first option “Open Package”. 2. Choose the original OS X installer.dmg or macOS Installer.app file from /Application folder. 3. Then browse through the contents and expand the Application folder inside the extracted .dmg or .app file to go to the Safari or you can simply type safari in the search box on the top right corner of the windows.

4. Right-Click or Control-Click the Safari.app and select install. It will install Safari to its default location /Application/Safari.app .

B.) Extract Safari from Hidden Recovery Partition on your Mac.

Recovery Partition is a small (650MB) hidden partition on your Mac’s internal hard drive which is reserved for common utilities such as Time Machine, Terminal, Disk Utility and other built in set of utilities as part of the Recovery System. It even has Safari. We can extract Safari from this partition using Pacifist , if the partition is accessible. There might be a possibility that your Mac does not have a recovery partition or the recovery partition is corrupt. You can check if your Mac has a recovery partition .

To access the Recovery Partition , you will have to first turn on the debug menu in “ Disk Utility ” as mentioned below:

3. This command enables the hidden Debug menu to appear in Disk Utility. Open Disk Utility and look for “ Debug ” alongside ‘ Help ’. 4. Click on the new Debug menu and select “ Show every partition “. 5. Now you should see the ‘Recovery HD’ in the left-hand pane of the Disk Utility window although it will be grayed out.

6. Select ‘ Recovery HD ’ and click the Mount icon, at the top of the Disk Utility Window, to make it active. After it is mounted, It will show up on desktop as a drive icon. 7. Now use Pacifist to extract Safari.app from Recovery Partition as mentioned below.

• Open Pacifist and click Open Package then select recovery HD.

• Once the BaseSystem.dmg is loaded you would see all of its contents. Select safari under Applications folder and then click on “ Extract To ” on the top and install it in /Application Folder.

#3. Reinstall OS X to Reinstall Safari.

If all the above steps have been tried out and it still does not fix the Safari issue. The last resort to you is Reinstall OS X to reinstall Safari, it will install a fresh copy of both your operating system and Safari and will not loose any of your files or document they will remain as is. Follow the step mentioned below for  Reinstalling OS X .

Restart your computer and hold down “Cmd+R ” together until you see gray Apple Logo. Make sure you’re connected to the Internet, select “Reinstall OS X” and click “Continue.” Follow the onscreen instructions to install OS X.

How to uninstall, reinstall, or reset Safari on Mac

Are you constantly trying to fix Safari on Mac?

Users who are plagued by Safari issues usually want to uninstall and reinstall the app to resolve them. While this might work for a lot of apps out there, it doesn’t quite solve Safari problems. In fact, you can’t simply click and delete the app since it is an in-built feature of the macOS and a permanent part of it.

Try Kingpin Private Browser for Free »

How do I uninstall and reinstall Safari?

If you are keen on fixing Safari just get the latest version of macOS and reinstall it on your computer to get rid of Safari bugs. If you are working with the newest edition of your macOS, you are automatically using the most recent version of Safari. This also ensures that user data like passwords and extensions are protected. Of course, if all else fails, you might consider using a different browser like Kingpin for high browsing speeds and incognito browsing .

How do I fix Safari on my Mac?

The very basic thing you can do is force quit the browser and hold the shift key when Safari is starting. This will make it start in safe boot. The safe mode is more stable than the regular one.

But this doesn’t always work. So you might need to tweak Safari settings to fit your usage . Resetting Safari on Mac clears the pile of cookies, caches, redirects, ad preferences, and a lot more. As we wrote in the previous article, it is possible to reset Safari browser even without opening . On the other hand, changing the settings may also cause you to permanently lose any data that does not have a back-up.

You can modify the settings easily after you’ve launched the browser on Mac. Here is a step-by-step guide to help you improve browser performance:

1. Delete Safari cache

Cache files weigh down your system like nothing else. You can find the ‘Delete’ option in the Preferences section of the Safari toolbar. Then go to the ‘Advanced’ tab and scroll down to the ‘Show Develop menu in the menu bar. Check the box in front of it. This will display the ‘Develop’ tab on the toolbar. Click on ‘Develop’ and then click on ‘Empty Caches’.

In short, here are the steps:

Safari > Preferences > Advanced > Show Develop menu in menu bar > Develop > Empty Caches

2. Delete website data

Every website you visit leaves some amount of data on your system. And all users visit a huge number of websites over some time. So, you can imagine the total data load that gets stored on your Mac.  It is easy to adjust the browser in such a way that all this data is removed and the browser malfunctions are removed.

Detailed steps:

• Launch Safari
• Click on Preferences to open a new window and then click on Privacy.
• Select the button named ‘Manage Website Data’.
• Click on the ‘Remove All’ button. You will be asked to confirm your choice.
• Click on ‘Remove Now’.

Safari > Preferences > Privacy > Manage Website Data > Remove All > Remove Now

Erasing website data from all websites you’ve ever visited might check the tracking issue. However, there is a potential problem of sites loading slower. Prioritize your needs and change the settings accordingly.

3. Delete Safari history

Safari settings on Mac make it easy to delete history files from the Safari toolbar.

Just do the following things. Launch Safari and click on the ‘Safari’ tab in the toolbar. Now click on ‘Clear History’. When the drop-down menu opens, choose ‘All History’ and finally, click on ‘Clear History’.

Like so: Safari > Clear History > All History > Clear History

4. Delete Safari extensions and plug-ins

To restore Safari settings and fix performance issues it is sometimes best to remove all extensions and plug-ins from the browser.

What to do:

• Open Safari on your system.
• Click on Preferences
• Head over to the ‘Extensions’ tab on the menu
• Here you will find the full list of active Extensions on the browser. You can choose to delete either a few selected ones or the entire list all at once.
• Click on ‘Uninstall’ to finish deleting them.

This is what it looks like:

Safari > Preferences > Extensions > Uninstall

Deleting plug-ins may be more tiresome than you think. They get saved in two separate places. Use your Finder window to locate them.

Here’s the outline:

• Launch Finder and move to the ‘Go’ option and select ‘Go to folder’
• In the search list that gets displayed, type ‘ ˜ /Library’ and click on ‘Go’.
• The Library folder opens and now it’s time to look for Internet Plug-ins saved in a different folder.
• Drag and drop them in the Trash.
• Next, go back to the ‘Go’ icon and type ‘Go to folder’ once again.
• This time you type ‘/Library’ and click on Go.
• Now you can look for the Internet Plug-ins folder once again.
• Drag and drop plug-ins in the Trash one final time to remove them from Safari.

Finder > Go > Go to folder > ˜ /Library > Go > Internet Plug-Ins > Trash > Go > Go to folder > Library > Internet Plug-Ins > Trash

With all such small modifications, you can reset Safari whenever you want. Once the browser is free of all this weight, it will not only become faster and lighter but also more secure than before. Some website data or extensions often download malware in your system.

Choosing an additional browser

Of course changing settings over and over again gets tedious. You might want to pick another browser like Kingpin that doesn’t store cookies or other site data . This saves you from having to tinker with its settings. Kingpin also forgets your browsing history and caches once your session is over. Moreover, the browser lets you access restricted content in private.

Having an alternate browser doesn’t hurt, especially when you can use it to perform highly-sensitive online activities like bank transactions or shopping for gifs without worrying about data leakage to other sites. Its tabs are PIN protected so no one can spy on you. With this browser, the chances of being tracked are minimized, which is a great thing since your browsing session won’t be broken up with ads.

Summing it all up

Safari is part of the MacOS and hence can’t be uninstalled or reinstalled. To get the maximum efficiency out of it what you can do is change Safari setting to suit your purpose. Remove extensions, caches, cookies, history, and all such files of little use. Keep your OS updated to enjoy the benefits of the newest version of Safari for Mac . As an alternative, switch to a safer, faster, private browser like Kingpin to fix all browsing issues once and for all. It is available for Mac and makes for an uninterrupted browsing experience.

How to Uninstall Safari on Mac

In this article you will find the following:

Safari, despite its reliability, trails behind with less than 20% of internet users opting to use the web browser. If your preferred browser isn’t Safari, then you’re likely ready to part ways with the app. With the help of our guide, we’ll show you how to block and delete Safari files from your computer.

Before we start:   Deleting apps on your Mac becomes a breeze with MacKeeper's Smart Uninstaller . This innovative tool is designed for efficiency, streamlining the overall uninstallation process. It also ensures a thorough removal, leaving no remnants behind.

• Can you delete Safari from Mac completely

No, you can’t completely remove Safari from Mac, and it’s all thanks to your computer’s System Integrity Protection (SIP) in macOS. SIP is like the bouncer of your Mac files, making sure you can't just kick Safari out of the club.

It’s not all bad news, though. Even though you can't permanently delete default Mac apps like Safari, you can still uninstall and block the app. These actions can limit Safari's activity and allow you to regain more control over the browser.

Before uninstalling Safari  

By attempting to get rid of Safari on Mac, you’re likely going to delete a ton of potentially valuable information from your computer. That’s why we recommend you begin with a checklist to help you tick off all the essential information you need to note down before proceeding with uninstalling Safari.  

• Write down all important Passwords so you do not lose them later on.
• Check your saved Bookmarks and note down any you’ll want to enable on your preferred web browser.
• Check your Browsing history for any important web address you do not want to lose. You can copy them into your Mac notes for safekeeping.
• Note down any installed Extensions or third-party Apps that you might forget to redownload after you remove Safari from Mac.

Tips from our experts:   If you are unsure how to remove extensions on Mac , this supporting guide will help walk you through the process.

1. Remove Safari on Mac with Terminal  

Removing Safari from Mac isn’t a task that everyone with an Apple computer will want to do. This is due to the removal process requiring you to alter macOS files that are protected by Apple. Still want to proceed with getting rid of Safari? We recommend using Terminal but make sure you have admin rights before going any further.

Here are the step-by-step instructions on how to uninstall Safari with Terminal:

1.1. Open Terminal

To delete Safari using Terminal, you’ll first need to open Terminal on Mac. Here’s how:

• In the Utilities menu, select Terminal .

To uninstall any Apple-protected apps with Terminal, you may need to turn off System Integrity Protection first:

• To disable System Integrity Protection, enter csrutil disable , and hit Return .
• Restart your Mac.
• Upon start-up, log into the admin account.

Once you're familiar with launching Terminal and disabling SIP, to enter the correct command to delete Safari from your Mac:

• Enter sudo rm -rf Safari.app/ and hit the Return key.

To re-enable System Integrity Protection, follow these steps:

• Type in csrutil enable and hit the Return key.

2. Block Safari

If you just want to block the web browser instead of deleting it, you can use your computer’s Screen Time function. This is a built-in macOS feature that allows you to control app usage.

Here’s how to block Safari using Screen Time:

• In the Apple menu, select System Settings .
• Select Screen Time , and click on App and Website Security .
• Click the Turn On App and Website Security button.
• Enable Content & Privacy Restrictions and select Apps .

If you use macOS Sonoma or earlier, you can remove Safari from Mac manually with your computer’s Finder tool. Granted, it’s not the fastest way to part with the browser, but it gets the job done.

Here’s how to manually delete Safari on Mac with Finder:

• Go to your Dock and open Finder .
• Click on Go > Go to Folder.
• /Users/ Your Name /Library/

Clear safari cache, clear safari preferences.

To delete browsing history on Safari, use these steps to guide you:

• Open MacKeeper .
• Select Safe Cleanup , and click Start Scan .
• Select the Logs, Cache, and Trash you want to delete and click Clean Junk Files .

To clear Safari preferences that, however, can influence how Safari behaves, follow these instructions:

• Select Go > Go to Folder .
• In the box, enter the path: ~/Library/Preferences/.
• Locate and remove any files starting with com.apple.Safari.

• Install a third-party app to remove Safari from your Mac

It can take five to 30 minutes to get rid of Safari on Mac manually, or any default app for that matter. If you have only a minute to spare, you may want to consider using a third-party app like Mac Keeper to help you remove Safari.

How to effortlessly delete any app using MacKeeper:

• In the Smart Uninstaller tab, click Start Scan .
• Select the app you want to delete and click Remove Selected .

• Safari cleanup unleashed

So, removing Safari from Mac is no walk in the park, thanks to System Integrity Protection (SIP). But worry not, as our guide has your back, walking you through all the tricks.

With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library. Then go to Preferences/com.apple.systempreferences.plist.  Move the .plist to your desktop.

Restart the computer, open the application, and test. If it works okay, delete the plist from the desktop.

If the application is the same, return the .plist to where you got it from, overwriting the newer one.

Thanks to leonie for some information contained in this.

also, in step 3 advised

• Open Google Chrome
• Push  Alt + F .
• Choose  Tools .
• Select  Extensions .
• Search for  Weknow.ac .
• Select  the trash can icon  to remove it.

but nothing happens when i press ALT+F and cannot find this tools menu otherwise.

Click on the link in the last line of my post, then follow the steps to go to Finder, remove extensions, and other items. Do not download any programs. Start where the screen shot appears in the article.

well, the malwarebytes is effective neutralizing threats, however, the random web ads keep appearring both in safari and chrome. i think the are coming from "MacKeeper." how do i get rid of this mess?

the only program that appears "suspiciously" is FLASH and thats when started having this problem. send the flash manager to the trash and emptied it, but flash still appears in "system preferences." how to totally uninstall?

If necessary, follow the manual instructions.  Do not download any other programs.
