How to remove Virus from USB Drives



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

USB

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.

Tweak UI

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.

    Disadvantage of using AVG Anti virus & AVG Internet Security
    –>If your pc RAM is lower than 512Mb<–

    ¤ Slow startup run
    ¤ Slow loading files/folders
    ¤ Scanning too long [about 1hr 30min ~ 3hr]

    If you want AVG Internet Security full [plus 3 choices]
    • Internet Security + Firewall
    • Anti Virus + Firewall
    • E-mail.. (I don’t know what it named) + Firewall

    I can give you. [Full license 28/02/2018]
    But I need some time for uploading the installer..

    Disadvantage of using Kapersky Internet Security

    Disadvantage of using Avira AntiVir (any type of Avira)

    ¤ Some program will detect as Trojan/Ad-ware.

    *Solution if want run detected program*
    1. Close Avira Guard
    2. Run the program
    3. After done, close the program
    4. Open Avira Guard.

    *Do not leave Avira Guard close for too long, this will cause Avira will not work anymore if not open back Guard..
    You will need re-install back if this happens*

    =====================================================================
    What I write is based on my experience..
