If you do not want to (ridiculously) try trial AntiVirus programs for 30 days, there are some online AV
websites that will use their tools to scan your computer -- right from your internet browser for free:
(they registered www.antivirus.com too)
Trendmicro scans and lists the viruses you have, you decide to clean, (or if impossible to clean) delete it.
Panda Software asks you what you want to do with the viruses on startup (delete or leave viruses alone but displays the viruses)...then it scans.
