When I startup gmer, I get a message saying "C:\windows\system32\config\system: The system cannot find the file specified." After clicking scan, the error comes up with the same directory except this time it says "The process cannot access the file because it is being used by another process." It then proceeds with the scan anyway and say the Gmer hasn't found any modifications. The log file is completely blank which I found strange. What should I do?
