Will doing a clean install of Windows 7 or 8 clean a pc that might be infected with a MBR rootkit?
The PC is a 2008 Dell Laptop with either XP or Vista. ( I think Vista). The user might have a rootkit and doesn't want to take the time or expense of going through a cleaning which might not work anyway.
Wondering if installing Win 7 cleanly would also write a new MBR or is fdisk /MBR needed?
If only fdisk /MBR will do it, maybe the better option is to do the fdisk and then use the Dell restore partition to get it back to original shipping-condition, perform all updates, reinstalls, etc etc.
