One of the ways by which a virus can infect your PC is through USB/Pen drives. Common viruses such as ’Ravmon’ , ‘New Folder.exe’, ‘Orkut is banned’ etc are spreading through USB drives. Most anti virus programs are unable to detect them and even if they do, in most cases they are unable to delete the file, only quarantine it. Here are the things which you can do if you want to remove such viruses from your USB drives


Whenever you plug a USB drive in your system, a window will appear similar to the one shown below

Most anti virus programs are unable to detect them and even if they do, in most cases they are unable to delete the file, only quarantine it. Here are the things which you can do if you want to remove such viruses from your USB drives

Don’t click on Ok , just choose ‘Cancel’. Open the Command Prompt by typing ‘cmd‘ in the run box. In the command prompt type the drive letter: and press enter . Now type dir /w/a and press enter.
This will display a list of the files in the pen drive. Check whether the following files are there or not

* Autorun.inf
* Ravmon.exe
* New Folder.exe
* svchost.exe
* Heap41a
* or any other exe file which may be suspicious.

If any of the above files are there, then probably the USB drive is infected. In command prompt type attrib -r -a -s -h *.* and press enter. This will remove the Read Only, Archive, System and hidden file attribute from all the files. Now just delete the files using the command del filename. example del Ravmon.exe. Delete all the files that are suspicious. To be on a safer side, just scan the USB drive with an anti virus program to check whether it is free of virus or not. Now remove the drive and plug it again. In most of the cases, the real culprit turns out to be the “Autorun.inf” file which mostly gets executed when someone clicks Ok in the dialog window which appears above. Thus the infections can spread

Security Tip
Disable the Autoplay feature of USB drives. If you disable the Autoplay feature of USB drives, then there are lesser chances of the virus spreading. A tool which can perform such a function is Tweak UI. Download it from here install it.

Run the program. Now you can disable the Autoplay feature of the removable drives as shown above. By following the above steps, you can keep your USB drives clean. If there are any other methods which you use, then share it with me through comments.

Second:

or the easy way (no software needed, just remember the process):

open my computer>tools>folder options

click on view tab, check display the content of the system folders.

under Hidden Files and Folders click on Show Hidden Files and Folders, then uncheck Hide Protected operating system files (recommended)

click Apply>Ok.

now you can view all the files in your removables.

precautions:

everytime you plug in your removables, do not, i mean do not just click on ok on the autorun process of Windows Eplorer. chances are if you click on OK, the autorun program which is being used by the virus and script in ur uremovable (e.g Autorun.inf, Ravmon.exe, New Folder.exe, svchost.exe) are executed and those names above is now in the process of infecting inside your PC without your knowledge.
to avoid this, cancel the Eplorer autorun window, go to your desktop (assuming you have plugged in ur removable), right click My Computer and choose Eplore. on the left pane of the Windows Explorer, click on your removable and there you go. you can now see those suspicious files inside in it. manully delete them all.

but the best way is, get an antivirus (e.g. ESET or AVIRA) and scan your removable for virus.

Third:

One of the easy way to stop autorun on your Machine (Windows XP Pro only)
is to use "Group Policy Option"

Assuming that your are the Administrator of your Machine!

Go to "RUN" and type "gpedit.msc" and click "OK"
On Group Policy Window expand "User Configuration"
Expand "Administrative Templates" and Click on "System"
At the right pane, scroll down and double click "Turn Off AutoPlay"
Click on "Enable" and at the DropDown Menu choose "CD-ROM" or "All Drives"
Good Luck!
