C:\ Access is denied

previous left arrow button next right arrow button
Everytime I click my Local Disc C:\, I get a "C:\ Access is denied" message. I right clicked the drive and found two open options. the topmost open option brought out the popup message and the 2nd open option opened C:\ normally.

I'm not really sure when this started because i don't often access C:\ from My Computer but just a few days ago, whenever i click C:\ in My Computer, i keep getting the "C:\ Access Denied" message. I have granted all my accounts access and I am also logged in as an administrator.

So I searched the Internet. And here's what I found out.

There is file autorun.inf in my root directory that commands my patition's behavior.
The content of this file is like :

[autorun]
open=virus.exe
shellexecute=wscript virus.vbs
explore=virus.exe

When I double click or open my partition, the file "virus.exe" is launched.

This file is created by a virus, first thing that I do is removing the virus before removing the autorun.inf file in all of my partitions. (Delete the file autorun.inf before removing the virus is useless because the virus will return it in its previous place a few seconds after its deleting.)

To know what's virus is on my root directory and to delete it entirely, I used USB FireWall
http://www.download.com/USB-FireWall/3000-2239_4-10817831.html
Launched it and then I clicked on "clean all partition", the software will posts a report. This software delete the autorun.inf file, stop the virus associated with it and delete the file (virus).

No Antivirus is reliable at 100%, sometimes, you have to get rid of virus manually or with the help of a fix or patch or an utility like USB FireWall or Flash Desinfector.
