Hi! I have Avast 4.7 professional edition (with all providers enabled). Lately i’ve browsed web site “japanrul.ru” with avant-browser (based on IE6) and got RSBOT virus. As soon as i got it my desktop became clear of any windows interface (no icons, no bars) - only background picture. I’ve rebooted in safe mode and kill “windows\msapp.exe”. Now my system is ok.
(finally, avast didn’t protect me)
May be this information will be useful for you.
Regards,
Monty.
