I am using win XP SP2, recently i have discovered that my pc is not letting me install any software like msn messenger, google talk, AVG anti virus. The error message it displays says that the file could be corrupt,or there could be some problem with the hardware or it could be the work of some virus. I was using Norton 2003 with Internet security pack. I thought it was virus so i took the system to my friends house and we cleaned bootsector with norton 2005. It didn't detect any virus but after the scan was complete we were able to install google talk and msn messenger but couldnt install AVG antivirus after uninstalling norton 2005 ( I don't know how it let norton 2005 to get installed for scan) since it was giving the same error message.I have scand for bad sectors too but could find any. Please help.

Most likely cause for not being able to install AVG is that Norton is not fully removed, and most AV programs won't install if they detect remnants of another one left on the system. Norton is particularly bad at failing to uninstall completely because it puts bits and pieces of itself all over your hard disk which the uninstaller simply can't keep track of. Acknowledging this, Symantec supply a removal tool and you can get it here:
