Due to the problems that have been described here, I've been thinking again to switch to another program. But I was pleased with Kasperski 2012 this year, I then but the full version of 2013 taken. I have rebuilt my computer this year in the spring with Win7 64 bit version. So there is still no other antivirus software on it was as Kaspersky. Unlike GData last year, I did not receive one hoax. For safety's sake I have backed up before installing the C partition. The CD starts automatically and there already a newer version is found, this has been downloaded and installed. The old version I have not been uninstalled. After restarting activation code is entered and updated the virus definitions manually. After another restart played Assassins Creed 2 (all settings on max) and in the background a video file from MP4 to AVI converted simultaneously. I could not notice any slowdown of my system. Even Firefox 17:01 works perfectly.
