What is Usbalex and removal instructions
Usbalex is a worm that spreads through floppy disks and mapped network drives. It also creates multiple copies of itself in some local folders and disks. Once executed, the parasite secretly installs itself to the system and starts spreading. Then it attempts to gather some system information and transfer it to its author. Usbalex does not carry any destructive payload. It runs on every Windows startup.
