your pc can be infected with a worm,trojan that can do this,it can be very hard to get rid of,try one thing,go to this site and download and run,
HouseCall - Free Online Virus and Spyware Scan

see if it can clean virus out pc.in your case dont do quick scan do the full scan.

but be ready to do a complete reinstal of windows,but drive will have to be scrubbed first.

Start in Safe Mode

unsure how?
Starting Windows XP in Safe Mode:

install your apps run scans with the anti virus spyware and malware software
remove any threats and then after that run ccleaner to clean your registry.

Hi,
If all of those softwares don't work, you have to format the Hard disk and then install windows.

thanks for help but no way .i had tried everything no success

As stated if you have tried everything just wipe it and reinstall your O/S.........................

Hii,
Attempted to clean with some live antivirus for example
Kaspersky rescue disk

[escaflowne]

the best option is to backup all your'e data and wipe the harddrive..
the same amount of time will go with the an anti spyware
and it's more secure
