ok I fixed my PC. do the following.
- Install SpyBot search and destroy. (download link provided in sticky thread here)
- when installing DO NOT select "upadate definitions".
- once installed go to download.com and download latest definition file and install MANUALY.
- goto programs and rename spybot exe file name and run.
This malware changes the DNS in windows system files, and also disables anti-malware and virus protection programs. Run SpyBot in administrator mode or else you won't be able to delete registry enteries.
in TCP/IP and IPv4 settings make sure DNS is not changed to something else. (in my case it was changed to 85.xxx.xxx.xxx.
your system should be ok after a restart.
