bo:heap memory virus

Sorry if I make a mistake or should not be starting a new thread, this is my first attempt at a forum. My son’s PC has been infected by the bo:heap memory virus. The virus was detected by mcAfee on the boot up scan, but can not be found when I manually run a scan. The PC is running windows XP sp2 and I have updated McAfee but it could not fix the problem. Should I start by following the instructions below from another thread. Any help would be greatly appreciated

Please download and install AVG antispyware tool
• Close all other Applications Select language click Ok
