Sounds like a trojan to me. If you do have a trojan/worm then,
-I'd suggest to do the follwing:
1. Stop System Restore
2. Download smitfraudfix, spybot, malwarebytes and CCleaner and have your antivirus
3. ReBoot into safe mode - Press F8 on startup and select Safe Mode (WinXP)
4. Run Smitfraudfix and update to latest signatures, then do the Scan and Clean - option 2
5. Now install CCleaner and do a clean of all temp internet files
6. Then install malwarebytes and upate and scan
7. Then do the same for spybot.
8. Then finally scan with you antivirus scanner
9. Once all the above comes back clear - Reboot Windows as normally
10. If the trojan exploits a Windows security hole, then the above might not clean it, and this would mean a complete re-install!!
Goodluck
IE8 is forced down via Windows update, but I have not had it come down on my PCs at home. I blocked IE7 & IE8 with a blocking programs, because as Abe and Family Dog, I'm a Firefox fan. Been using Firefox for 5 years and had no issues, except maybe the odd extension causing hassles.
I have also tried Google Chrome, but its not there yet.
