Hi everyone I'm getting an error message when I log on called MOM.exe anyone have any ideas about what it is and what I could do to get rid of it?

Strongly suggest visiting this link:

Spyware.Mom - Symantec.com

Hi I have been reading around and I have read that it could be part of the ATI Catalyst Control Centre?

It was probably a hole in the current version of ATI Catalyst Control Centre software. The keylogger (mom.exe) took advantage of this.

However don't be misled by this. The initial diagnosis is still that it is spyware. I'd run Ad-aware and Spybot, then visit Symantec to rid your computer of it.

Cheers
