recently my pc which uses win2k3 running much slower then it was, and noticed in the task mangager that cpu usage had always stay up at 100%, the file that used the most is a file named izoqqi.exe, i haven't seen it before, and it mostly used above 90 of cpu resourse, i tried to end it, but it'll appear again shortly, i found that is resides under the windows/system32 path, and even i tried to move it to a different path, when i run it, it goes back to it's path, and i can't delete nor do anything about it, do any1 know is it a virus, backdoor or a normal application that are under protection?
