Nowadays, most of the viruses/worms spread via USB drives. So, now if your USB drive is infected and if you double-click it to open it… BOOM the virus enters your drive. Unless your AntiVirus is updated till date, you don’t have any means to identify whether there exists an infection in your USB drive. Even if your AntiVirus IS updated, chances are that the virus/worm is a new one and your AntiVirus doesn’t have any record of it. So how do you decide whether your USB drive’s infected or not without relying on your AntiVirus??
