NTVDM problem

[Guest]

I typed in cmd.exe into my Run box to get the command window. I need it to
fix my router, but whenever I type in a "ping" command, the program freezes.
In the task manager window under "CPU" the number I see is over 90 for the
program ntvdm.exe. How do I fix this?

You got ping.com as part of a trojan/virus/worm.

Update your antivirus software and run a complete scan.

Update whatever anti-spyware applications that you have and run a full
system scan with each one.

[[This worm drops the legitimate file compression DLL, BSZIP.DLL in the
Windows system folder. It does this so it can compress itself. It also drops
the following files in the Windows system folder:

CMD.COM
NETSTAT.COM
PING.COM
REGEDIT.COM
TASKKILL.COM
TASKLIST.COM
TRACERT.COM

These files contain the string MZ so that this worm can disable the
following Windows tool applications:

CMD.EXE
NETSTAT.EXE
PING.EXE
REGEDIT.EXE
TASKKILL.EXE
TASKLIST.EXE
TRACERT.EXE ]]
