How to scan computer ? what is the best Antivirus?

I like norton the most but any other that is free is also ok just do a full system scan. You could also use trojan remover which is free to download to fix the worst problems and ccleaner to clean up a bit.

well, i suggest u to try bit defender or AVG9. u can try it for 60 days only. or u can try looking at piratebay.org. there u can download lots of antivirus for free. its a full version. also, u can try looing in download.com or cnet.com. just follow the steps on how to download it. if u want to scan your computer, u must have an antivirus first. just look for scan my computer and go!!! its willstart scanning your computer.
