Wow, 1,760 infections?

I hope that was a typo or your computer was in serious trouble. As for not disabling what you don't recognize, you shouldn't be too worried as you can always re-enable what you want to turn on. The reason I told you to do that is because if you don't then the Anti-Virus XP is turning itself on when ever your computer starts making it more difficult to be removed. Also you don't know what else you have running.
It is odd that you are still getting redirected after you ran the scans.
