I am de-virusing a clients compunter, he got the 'Department of Justice' screen lock virus.. I'm following the Hitman-pro anti-malware and created a usb bootable.. however my laptop is 64 bit win 7.. he's running a 32 bit win xp.. How do i install the 32 bit program on the flash drive to get his to boot from it? Aside from buying a 32 bit machine
