Why didn't you go back to using KAV after trying AntiVir? Don't you feel a lot safer with KAV's PDM feature protecting you while you're online? If you're paying for the AntiVir PE edition, you don't even get free email tech support. Instead, you have to rely on a slow responding forum, where your problem can be ignored. With KAV, at least you get to email a tech if the forum can't help you. How much more stable is AntiVir than KAV, as far as it not having bugs that cause problems, etc?
