Hello, I have a 2.0 Pentium 4 with 80GB HD and 512 MB ram. My computer has been running fine for the past year, but this weekend it seemed to have caught a virus or something.
I have been spending the last couple nights trying to solve the problem. I recently installed Symantec Antivirus Corporate Edition, but I think its scanning is slowed down by my computer.
When I open up the Windows Task Manager, my CPU usage is always (since yesterday) 100%!!!! I then tried to look at the processes to look for what is sucking up my mem usage, and came across something very odd... When I sorted them from highest to lowest in "CPU" column, I see processes such as "TqFgN9.exe" , "Yco0b3.exe" , "Ozfgq88m.exe" , and "XxxohNxV.exe" . As soon as I end these processes (they usually take up about 80 CPU) they magically reappear a few seconds later! My CPU usage goes down to around 7% for that short time untill it comes back or another process takes its place. I tried searching for those files on my computer, but I could not find them, only a .pf file. What is that?
I have been running Ad-aware for a few months now, and it hasn't caused me any problems. I ran it Friday night, and afterwards I noticed a significant decrease in system performance. It said it could not delete a certain .dll file, but that's all I can remember... Is it typical to see slower performance after running ad aware? I've restarted my computer a number of times.
I installed spybot-S&D and ran it and it didnt seem to help at all.

Please help me!!! I miss my fast computer........
