Go to AVG's homepage and look for a removal tool. Uninstall the software and download Microsoft Security Essentials...It's free and perpetual. You may also consider upgrading to Win 7 or downgrading to XP. Vista is the reason many folks are back to XP and Microsoft's reason for creating Win 7.

open services.msc from run window and then find avgwdsvc.exe. right click and select properties then check the disabled checkbox. Apply and get out of services.msc. now try to install the new version of avg.

Sounds like you did not do things in the correct order or you did not reboot between the AVG uninstall and the Kapersky install, so that it looked like AVG was still loaded.

Since Kapersky is not installed, the best way to proceed is to start from a fresh reboot, download and re-install the AVG free edition to get the registry entries corrected. Don't bother with updates as it is coming back out again. Reboot and uninstall AVG. Reboot again and verify AVG is gone before attempting to install the Kapersky.

AVG free can be downloaded from free.grisoft.com assuming you mean the 8.0 version, not 7.5, otherwise try downloading from www.filehippo.com and select the older version.

if you have an anti virus programme installed, start your pc in safe mode (F8 while booting up) and then run your anti virus and anti spyware programme and also check your temp folder for suspicious folders dated arond the time you downloaded, the only free good anti virus programme is AVG 8 free if you don't have one.

Norton Antivirus is a bit of a system resourse hog, try AVG 8.0 free version it is a lot better. I run it on all my machines.
