Thumb driver users be aware, you might be unwittingly spreading winantivirus
2009. Inserting a thumb drive into an infected machine (of at least one of
the variants) creates a hidden pair of files on the root directory.

i) m.exe hidden and claiming to be from skype
ii) autorun.ini which is set to silently run m.exe whenever the drive is
inserted.

The only clue you will have this is happening, is a second or so delay
between clicking on the thumb drive, and it opening.

AFAIK it puts files in the system32 folder (in this case fffcaf.dll, but
that might just be a random file name) and puts multiple start up points in
the registry.

Anyone know of any usb thumb drives with a read only switch?
