Constant Win32:Trojan-gen. {UPX!} viruses

[Dameon]

I keep getting virus alerts every few minutes. Everytime it is a Win32: Trojan-gen. {UPX!} virus. I am running Windows XP Pro SP2. They always appear in my Temp folder and even though I have cleaned it out completely exe files keep on appearing there. They also seem to have a random name that is a combination of letters and numbers that don't turn up on google. For example, the latest one is "OLBje1.exe". I alsways move them to the chest but new ones keep appearing. What do I do? Thank you.

I suggest you start with cleaning your system.
