I've been picking up new viruses, it would seem at least once a day. I have cleaned my system as well as I know how to, my hijack log has been posted, and cleaned, and since that nothing that shouldn't be there has popped up..Occasionally a file called 5bt5.exe will reappear in task manager, I will delete it, and all references to it..and days later it returns. Another file that sounded fishy was c:\\sys_ai_client_loader.exe.( I don't know what this is, so I don't feel safe deleting it.) From what I have read online, people who have it are told to delete it, but I am not sure. I just dont understand what is causing the viruses..I never! dl anything for fear of just that.. The original virus that started this mess was caused from reinstalling windows and forgetting to update to sp1 (windows xp). I also keep getting spyware dled onto my computer, (which was never a problem before I reinstalled), and have spybot constantly checking for them.

I hope someone can help, because I can't seem to get a response on any other forum..
Thanks!
