From my personal usage experience, I’d like to mention, that screen-saver function was new for me, also its really usefull. It scans your hard drive, while your pc is in screen-saver mode. Virus database is updated daily, good virus/spyware support. Once I sent to Alwil software sample of spyware file, which was not detected. Next day it was detected as spyware! Also there is very handy feature for windowsXP boot-time scan. Even when virus is still active and cannot be deleted in normal windows mode, you can schedule boot-time scanning, so after reboot avast checks whole your drive before os boots-up.
