What's a really good free spyware and virus removal?

I don't have alot of money to pay for the big companies subscription based antivirus software so I'm looking for the best I can get freeware or otherwise. Prevx worked well but I used up the 30 day trial. Also have spybot but that's not doing so well either. Any other suggestions?
