Are there any good ones that do the job correctly? I can't seem to find a decent one, all are test them out, you have 19,000 errors fix them for 97$ which sucks ass. My main comp is riddled with reg errors and virus'. Kids been playing on them along with other family members. I had zone alarm Firewall and AVG but AVG seems to pick up on the non-virus' and let the harmful ones in. Any help appreciated!
