I am a little worried and sometimes hesitates that maybe some anti-virus or Anti-spywares may make a mistakes of identifying a "good things" as bad. (Coz my experiences w some of the most trusted Registry cleaners made me more aware though that this can also will possibly happens to Anti-virus and Anti-spyware scanners). Aside from my main Antivirus Avast Home, I also uses several on-demand virus scanners like BitDefender 8, ClamWin, Dr.Web, and Kaspersky free just like I also uses several Anti-spyware scanners. BitDefender can always find several viruses and ClamWin can sometimes find a Trojans in my pc. While some of my scanners couldn't. What's your personal opinion on this .. is it always ok to trust their findings or is it more better to always make settings to Quarantine their findings instead of automatically disinfecting or deleting them?
