Ping.com is added by a trojan/virus/worm. Ping.exe is the correct file.

You probably also have cmd.com that is added by a trojan/virus/worm.

Typing cmd in the Run Command probably tries to open cmd.com instead of
cmd.exe.

..com files are executed before .exe files.

Typing cmd.exe in the Run command may open cmd.exe.

Typing %windir%\system32\cmd.exe in the Run command may open cmd.exe.

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.

In news:6D1664CB-9E49-43A5-BED2-238D29CAE619@xxxxxxxxxxxxx,
EARaddar <EARaddar@xxxxxxxxxxxxxxxxxxxxxxxxx> hunted and pecked:
I tried to run cmd from the run command and I got an error message saying
that cmd is not a valid win32 Application. While trying to figure out what
the problem was, I discovered that my system32 folder was hidden and had
the hidden check box disabled. I was able to open cmd from inside the
folder (by double clicking on it), it worked, but many commands would not
work e.g. ping.com.
When I checked the system32 attributes from DOS with the attrib coomand
the folders has SH as its attributes. I tried to reset these attributes
with the attrib command again but it will not reset.

Anyway, the question is, what is the cause of this problem and how do I
solve it?
By the way, this is clean system with latest updates and service packs.

Thanks
