Problem with command prompt

When I try "ping....." or "cmd" in "Run....." from the start menu, this shows up

Can anybody help me resolve this problem?

Thanx!

 

ping only works from a command console.
If run doesn't want to bring up the console, just look for it under start>all programs, it's in there somewhere.

 

I tried it from command prompt in accecories, it gives me the same messege.

 

That's odd, it should just point out the correct syntaxis to use the ping commands..
Are you on a restricted account ?

 

Nope, this started happening a few days back when this happened Click here

But that problem has been resolved now.

 

Search your computer for ping.com and delete it.

The vast majority of DOS commands are exe files, so if there's a matching .com file, Windows will try to run that file first. It's usually a leftover from a virus or other form of malware to prevent you from running DOS commands that could eliminate the threat.

Same for:
regedit.com
ping.com
msinfo32.com

etc....

 

I can't find nothing of that sort

 

Morph & Fiend: you still got this one, im working with a few others. Can he do a start run regedit? Sounds like somebody turned off some shell extensions.

 

Plz help me as soon as possible guys!

 

Have you run any virus/malware scans to make sure nothing is corrupting the files?

 

Yeah, I ran AVG anti virus. Maybe it deleted some important files or something

 

No single app will pick up everything....try running some ad/spyware apps to see if they pick up anything.

 

Can you recommend me some good ones?
