Answer : trojan.startpage keeps coming back

Before cleaning the system make sure that you have disabled the System Restore >> http://www.pchell.com/virus/systemrestore.shtml
After that Download these tools, install and update them:
========================================================
AdAware ==> http://www.spychecker.com/program/adaware.html
SpyBot  ==> http://www.spychecker.com/program/spybot.html
MS Antispyware ==> http://www.microsoft.com/athome/security/spyware/software/default.mspx
CoolWebShredder ==> http://www.softpedia.com/public/cat/10/17/10-17-150.shtml
Stinger ==> http://vil.nai.com/vil/stinger
========================================================

Then Run all of them one by one in safemode and delete everything they detect.
Then delete the temporary internet files and history of IE
and run Disk Cleanup on your hard drive to delete those temp and junk files.
Restart back in Normal Mode to check for the problems now ?? :)
