System restore deleted a file.

I downloaded a anti virus setup file in my documents on Wednesday
(norton.exe). On Thursday I used system restore to Tuesday. I noticed that
norton.exe disappeared. I used system restore to come to Thursday, but
norton.exe never came back. I am using vista business. Can someone help me
solve this mystery.

Hi Harpreet,

Norton.exe is usually the Ahker worm, you wouldn't want it back. More here:
