Hi I was wondering if anyone can help me, I've done a bit of searching but to no avail, I have a friends broken down windows XP machine she informed me it keep going to porn sites via redirection. So I figured I would remove the hdd and service the PC inside while I was at it, well I figured I can scan for viruses from my macbook pro using a usb connection from the hdd to the macbook so I hocked it up and my macbook reads it as an external drive, but clamXav can't remove any of the viruses from the hdd as I'm not the owner of it, now is there any way that I can take ownership like I can in windows and remove the viruses from there hard drive? or is this is impossible on a NTFS formatted hard drive? Some side notes the Hard drive is the main boot drive for there system it's windows XP NTFS, and I'm running OS X lion on a Macbook Pro. Any help would be great!
