Spreads via€¦
Removable and network drives
Worm:Win32/Vobfus.XQ can create the following files on targeted drives:
:\i love you.exe :\koaru.exe :\naked.exe :\password.exe :\subst.exe :\webcam.exe
It also creates an autorun.inf file in the root folder of the removable drive. The file has instructions to launch the malware automatically when the removable drive is connected to a PC with the Autorun feature turned on.
