@ prog-bman :
how to remove it, please help ?

http://www.lavasoftusa.com/software/adaware/
http://www.safer-networking.org/en/index.html

Run one, or both of these programs and see what happens. Also try runnnig a virus scan and monitoring the programs currently in memory, starting up in msconfig, and entered into the run keys in the registry. Look for suspicous entries.

@ Shadow :
Thanks, but these two software not free,
can you suggest some freewares ?

AdAware's free.

so is spybot

Thanks to every friend:

1, enter IE's property ,
2, enter web safe ,
3, enter restricted website ,
4, include above two websites in restricted item.

True it can be that your homepage is back to normal but you didnt solve the actual problem, it is still there but you are just covering it up by going around the problem....

I personnaly would still look on how to completely get rid of it, in the meanwhile you can indeed use your method, but for "Computer´s sake" try and get rid of the actual problem....
