Autorun.inf Worm infecting removable USB drives

Few days ago, i met an unknown friend whose pen drive got infected with a strange virus/worm. I didn't know at that moment what was the problem. I gave all possible solutions to him but it seemed he tried them all. Now, it's the recent threat and circulating around the world.

This Autorun.inf worm is technically called w32/SillyFD-AA which installs itself onto systems and also puts a message in Internet Explorer reading 'Hacked by 1BYTE'. It also installs an autorun.inf on any removable drives, such as USB sticks or floppy discs.This worm gets automatically installed on new computer where the infected drive is inserted. The effect of this worm can be seen at Internet Explorer's title bar and annoyance is we can't perform regular file/folder actions so easily.



Besides, the way it gets transferred is as same as we did experienced with the virus getting transferred from floppy diskettes. At least floppy disks would allow us to write protect but in USB drive's case? we don't have an option and so it's the most vulnerable storage media for transferring worms.

Solution and best method to be safe is to disable the autorun feature in Windows XP or any other OSes. Then delete the Autorun.inf from the removable drive's root folder.

And Sophos antivirus claims it can remove this worm successfully. To download the trial edition, check this link
