[Tatsat]

I have a geniune Windows Vista Home Basic installed.There is a fake warning saying"Your windows will expire in 0 days.Kindly reinstall any version of vista.And after 1 1/2hr of this warning the system restarts and sometimes hangs.I m using Avast Home Edition Antivirus.

Download Kaspersky Antivirus or eset NOD32 antivirus. Then download Spybot Search and Destroy, Windows Defender and Spyware Blaster
Make sure Spyware Blaster is updated. Also download Comodo BOClean
First, delete Avast. It is too wimpy. Then install free trial of Kaspersky AntiVirus or ESET NOD32 antivirus. Make them do Full Computer Scan of any viruses or rootkit. then use Windows Defender to do a Quick Scan of the system. Update Spyware Blaster to a scan. Delete anything those programs scan. Then after installing Comodo BOClean, Reboot the system. Then do a scan. Delete anything the program scans. That should help the system.

Vista Home Basic. Original.
Activated?
Installed SP1 Beta by any chance, if so uninstall it.
