Anti-virus USB drive from IOCell

IOCell is featuring a USB drive with anti-virus software called the Vaccine Drive. It holds an auto run anti-virus engine which activates when connected via USB to the host computer. The drive will then scan the system and also provide real time monitoring of the memory and processor. Since the Vaccine resides outside the OS there will be no software collision if two anti-virus programs are running simultaneously. Virus updates for the Vaccine Drive seem one step behind, would the virus hit the host computer before the drive was getting it’s update? Hmm…
