PC Pitstop Analysis

winlogon.exe file name used by the WinLogon trojan has the same name as a legitimate Microsoft file. However, the trojan can be identified by these traits: it does not contain vendor/product information saying it is from Microsoft; it is installed in a directory other than Windows system32; it is always running and often uses large amounts of memory and cpu time. If the file information does not show the vendor being Microsoft, then this is most likely the WinLogon trojan.

winlogon.exe is a VIRUS. Stop all work until the virus is removed or you run the risk of spreading the virus to other people. Worse yet, the virus may be doing harm to your computer and your information.
