For protecting our computers from security and malware threats we sometimes experiment with different security suites to see which one is better than the other. In this process, we install and uninstall these security suites as it is always advisable to use only one antivirus or a full featured security suite at a time in our system. More than one antivirus or a full featured security suite that includes everything from a firewall, antivirus, anti-spyware, anti-malware, and more can cause lots of performance and stability issues.

Although we can easily uninstall the existing security program using Windows built-in “Add/Remove Programs” (or Programs and Features in Windows Vista and 7) applet but it’s not a perfect solution. Sometimes the uninstaller of the program doesn’t remove all the components and registry keys installed by the security program completely, this can hamper with the newly installed security program and may even cause system instability and BSOD’s.

What should we do then? How can we uninstall the existing antivirus or security suite completely? Well, almost all the security suite vendors provides a special uninstaller tool which can remove the security suite completely from your system. We are here providing a list (not in any particular order) of these special uninstaller of all popular security suite or antivirus programs to save you time and energy in finding them yourself.

For most of these uninstaller, you just need to run the executable file and follow the onscreen instructions. Then after completion, restart your system to have a clean system again.

  4. Amazing article with a lot of useful information, actually, recently I’ve found another way to speed up my poor PC, the software “tuneup360”. It’s very easy to handle and of course very powerful, my friends and I all use it now, maybe you can have a try.
