I’ve run out of NOD32 license so I’ve downloaded Avast Home/Professional version. It is friendly, fast and seems to know a lot. So I’ve installed it and I was totally happy.
After a while Chrome started crashing randomly. I couldn’t even kill chrome process, not even with Process Explorer. Restarts helped, but just for a while.
I found forums about the same symptoms with Firefox, and a few with Internet Explorer. I’ve already uninstalled Avast and I’m moving back to NOD32. Safe, fast and simply works. I will never use free antivirus software again.
