If my calculations are correct, your comp gets infected by
spyware/adware/malware/virus/worms/trojan on the average of 3.5
days. 
Do you just go around d/ling and installing every single thing that
seems like some spyware/adware/malware/virus/worms/trojan removal?
If you have such a habit, I recommend you use NOD32 over Avast.
Yes, you have to pay for it.
