How can I disable the Windows XP System Restore?

I had a Malware attack and I can’t seem to delete it. I already run my Antivirus software few times now but it didn’t work. Until I found out that it is hidden on my system restore area. And I can’t find a way to delete it. I want to know how I can temporarily disable my System Restore. I am running Windows XP Pro Service Pack 3. Please send me some help. Thanks.
