Hi friends. My computer just got this weird virus from my roommate's lappy. Whenever I plug in any usb drive, all the contents of that usb drive gets hidden and shortcuts are created. Although I can access all the files by using the option 'Show hidden items', but I thinks it's good if that option remains closed. . The problem exists only with removable drives. Files on hard disk are fine.The most frustrating part is that my avira antivirus is fully updated and still it's unable to detect anything suspicious. Please help me.
