Hi
This is probably beacuse you have a spyware/virus or trojan
which adds hosts to the hosts file.
Basic programs:
- An updated antivirusprogram
- Firewall running
- MSAS installed and all scans in "full system scan".
- Lavasofts Adaware for redundant extra manual scans:

- CCleaner for removing temporarily junk

- All above scans can also be done in safe mode for better result.
- After cleaning, hosts file reader and reset ( this can be done after
malware removal)
