Need an advice on antivirus software

Guys, looks like my NOD32 failed, i got a Windows error message every 40 minutes and have to shut'em down.
Grrrr...that NOD32 is so ****ng famous, it gets No 1 in almost every anti-virus contest, but now =\ Can someone suggest a really working anti-virus? Not this fast lazy-idiot.

sorry for posting it in "Spaß/Off Topic" topic and offensive language, i'm completely pissed off =(
