You can delete a system file in XP nothing will prevent you. But after a second or two the file will be regenerated by Windows. Why its this way?
I've installed Norton Anti Virus on my uncle's PC. It warns him each time it dials up for internet. It says IPv9.dll is infected and deleted automatically. But AV doesn't know that its a system file and will be regenerated by OS. The problem is that it seems that the regenerated file is also infected. What can I do with it?
[Edit] The System Restore was disabled on his PC.
