Hi KASHIF AHMED,
Sounds to me like your computer is suffering from a malware infestation. I
would recommend posting your question at a forum that deals with malware,
such as the AUMHA Forums' "Parasites - Adware, Spyware & Other Scumware"
forum:
http://aumha.net/viewforum.php?f=28
You have to register to use the forums, but registration is free.
Regards,
