Ok all of a suddden after not being at the computer for about 5 minutes it "switches users" and brings me back to the welcome screen but doesnt log me out so i can just go back in but its pretty annoying.

How can I fix this

You have blaster worm most likely.

Hmmm Virus scan with Mcafee and nothing found.

 

[nweaver]

screensaver option, look in display properties.

Oh, yeah, I think mweaver is on to the problem. I forget about the nuances of XP Home.
