Guest web_poster03@yahoo.com Posted September 25, 2007 Posted September 25, 2007 from Start -> Run: type the full path to execute c:\WINDOWS\system32\cmd.exe, I can get the Command Prompt window. Type cmd.exe only, then the Command Prompt window flashes and disappears right away. What is the problem? TIA

You should hunt it down and at the very least rename it to render it harmless.

Thanks for your suggestion. That is my suspect too. My computer recently was infected by VBS_PSYME.gen file. I could not find any other cmd.exe file except for in the windows\system32. I found 2 strange things: 1. if I cd back to C:\, the window will be closed. 2. if I type "echo" command, the window will be closed too. Any further help will be appreciated.

If the current window closes each time you type "echo" then your command processor is compromised. You could do this: - Run sfc.exe /scannow from a Command Prompt. - Use System Restore to return your machine to a point well before these problems started.
