This question is very common among users so I’ve decided to give you a few hints about where that nasty infection came from.
Every user has different internet related habits, some can be benign and some can be very dangerous. As many of you know, malware creators target only the most popular internet places so don’t be surprised when you take a look at this list.
1. XXX , Porn sites
2. Warez , Places that distribute pirated software, movies, music…
3. P2P, File sharing networks
4. Social Networking Sites, MySpace, Facebook, Linkedin, Twitter like places
These are the very top of “malware distribution centers” , so if you visit one (or all) of the places listed above it is very possible that your computer is indeed infected with some form of malware.
