When networked computer immediately connects to malicious sites.

I found some similar symptoms on this site and started corrective action.
This is what I have so far:
Computer Info:
  SONY Vaio w/ 2 gig ram  300 gig Hard drive video is nvidia geforce 750 gtx

OS:
 Windows XP Media Center Service Pack 2
Original operating system for computer.
I do not have a recovery DVD the system has a partitioned hard drive for recovery. (Recovered last week)
Automatic updates are on and installed regularly.

Anti Virus:
Used to run spybot
Just changed to AVAST I like it better

Actions:
Avast scan in boot mode found several hundred files for malicious programs and deleted them.
I can not connect the computer to internet for more than 5 minutes or it will Max out the CPU usage.
