So... Is there such thing as a good virus?

USB flash drive worm spreads information about AIDS.

Sophos is reporting a worm which spreads by copying itself onto removable drives such as USB flash drives, in an attempt to spread information about AIDS and HIV.

The W32/LiarVB-A worm hunts for removable drives such as floppy disks and USB memory sticks (as well as spreading via network shares), and then creates a hidden file called autorun.inf to ensure a copy of the worm is run the next time it is connected to a Windows PC. Once it has infected a system it drops an HTML file containing a message about AIDS and HIV to the user's drive.
