0 See Running Viruses

Stop getting tricked into running viruses because you don’t see the file extension of an attachment.

Click Start, click My Computer, and on the Tools menu, click Folder Options.

Clear the Hide file extensions for known file types check box, and then click OK.

Now when you receive a file called something.jpg.vbs, you’ll see the .vbs extension and know that it is not an ordinary .jpg file.
