Actually, I'm quite aware of viruses and spyware. I was actually a BETA tester for F-Prot in the early 90's. However, there are some new friggin' viruses and spyware that are so advanced that they can't be detected at all and F-Prot/F-Secure is aware that they are out there. I am just not taking chances.
FirstClass, I highly recommend downloading F-Secure Internet Security 2008 and run a complete scan on your system. It's the finest anti virus/spyware program ever made. They're made by the people who made F-Prot, and I highly recommend it. There is a high chance that it'll detect some virus or spyware on your system.
Let me tell you that I ran Adaware and Bazooka and they failed to detect many spyware on my Dad's laptop. F-Secure detected a lot that were missed by the Adaware and Bazooka.
