Normally, I don't have problems beating viruses made by most people, but this one has me stumped. First of all, it disables the regestry, so I can't kill it there. Second, it won't let me kill the process. Third, it shuts down my computer every couple of hours. It also spikes the system resource usage to 100% every few seconds. The name of the process is winudpa.exe. I know where in c:\windows\system32 the exe file is, but of course i can't delete it cause it is running. Anyways, anyone have any ideas of how i can beat this. Did I metion that none of the virus scan programs will pick it up. Please help someone.
