Unless those are coming from someone you know REALLY well I would toss them. I don't see why someone would be sending you a .bat file. Correct me if I'm wrong but you should be able to look at the batch before executing it. If you're seeing things in there like "deltree c:\*.*" then you should probably just toss them :). __________________________________________________ Do You Yahoo!? Yahoo!
