Portable scandisk, spyware & malware intact with anti virus software.

I am in favor of a portable scandisk to run a scan on a drive, be it hard drive, or the usb flash drive itself. This would be very helpful, as my inlaws comp wont run a scan disk or defrag, but with the portable defrag program, it defragged! Also I am in favor of a malware, adware, and spyware removal app. This would help alot as I know alot of people whose computers are infected and don't even know it until a scan is ran.
