# "Vosate Nofooz" - an almost unknown iranian malware [ part 1 ]

Well, after took some glance at this malware, I've been decided to write up something useful for this kind of almost unknown malware .
the term "unknown" is not referred to something dangerous with the high level risk !
actually this malware doesn't dangerous as people have thinking about it, this kind of malware is difficult on the cleaning phase .
the malware doesn't act as so dangerous code, but it's robust in the field of self-defense .
the technical name of this variant is "W32/AutoRun.gv", as you can see and search over various search engines there's a few results available to this Worm .
the executable name of this malware is "explorer.exe" .
the actual path is "C:\explorer.exe", it's a hidden file which you can see it with the help of 3rd party anti-malware softwares such as Malware defender .
yes, you guess right ! it's an autorun worm, whenever you put your mass storage device onto the usb port it will spread itself to the usb drive with the following name and format:
%RemovableDrive%\Autorun.inf
%RemovableDrive%\explorer.exe

there are also other files that is act as this worm :

%Temp%\MMBPlayer\i.JPG
%Temp%\MMBPlayer\Systools.dll
%Temp%\MMBPlayer\wallpaper.dll
