My friend you have to stop this guy from using your PC for his raunchy deeds. It is destroying himself (psychologically) and can possible expose you to horrible things like identity theft and fraud, because I will never use the same machine for doing online shopping if I know someone else is using it for porn.

No security application is perfect and exposing it constantly to these sites will eventually have one slip past your defences. Remember any anti-malware application is one step behind malware developers. A new threat first have to claim a victim before it can be analysed and added to the virus definitions of the anti-malware product, so no matter how good your anti-malware product is, if it doesn't have a specific threat in its database, it will get through.
