Who hasn't experienced his computer popping up windows, being slow with strange new programs in your start menu. If that's the case it's likely that you're computer is infected with a virus, trojan or spyware.
I'm writing this article because people keep asking me the same questions and I hope this can provide further help.
This article covers a very wide area in a short period of time so it assumed that the reader has at least basic computer skills.
