Im trying to fix a friend's computer. Theres a program called pbrrol.exe thats in C:\WINDOWS\System32 that wont let firefox to load. The windows task manager doesnt show it, I have to use the task view from the makers of HiJack This to see it. When I end the program with the secondary task manager Firefox loads no prob otherwise it doesnt show but firefox.exe shows in the task manager. I cant find the file in the folder, I can find it with windows find, but when I delete it, it respawns. Another file appears in the registry for startup - rikk.exe. This file is loated in the startup folder but cannot be seen even with show hidden file (shows via Windows Find). I've ran adaware and spybot to no avail. His laptop runs Windows XP Pro SP2, he uses the windows firewall.
