    Good day!

    I lent my USB Flash Drive to a friend for one day so she could use it for her laptop. When I got it back and used it in my computer, a Symantec window indicating that it had 'caught' a trojan named Trojan.Perfcoo kept popping up, and the computer speed decreased significantly. I restarted the computer, but this message keeps popping up: "The application or DLL C:\WINDOWS\system32\perfc000.dat is not a valid windows image. Please check this against your installation diskette."

    Thank you in advance for any help! :)

    Did you follow Symantec's instructions here:
    http://www.symantec.com/security_response/writeup.jsp?docid=2007-052413-4115-99&tabid=3

    Are your antivirus prorgam and definitions upto date?

    You are not using the current version of the tools from the READ ME. You attached logs from versions of ShowNew and GetRunKey that are almost a year out of date.

    Why did you have CounterSpy ignore what it found? There is no sense in running the scans if you do not fix what they find.
