Hi my dear friends many of your PC/laptop’s normally gets virus because of Pen Drives or USB devices.
Some Virus like Ravmon Virus, Heap41a worm which are not detected by anti-virus normally spreads mostly by the Pen Drives.

In such a case what can you do to prevent your Personal Computer or Office system from getting infected with Virus that spreads through USB devices or Pen Drives???

Tips to protect your PC:

Connect your Pen Drive or USB drive to your computer.
Now dialogue windows will pop-up asking you to choose among the options. Don’t choose any of them, just simply click Cancel.

Now go to Start–> Run and type cmd to open the Command Prompt window.

Now go to My Computer and Check the Drive letter of your USB drive or Pen Drive. (For E.g. If it is written Transcend (I:),then I: will be the drive letter.)

In the Command Window (cmd), type the drive letter: and Hit Enter.

Now type dir/w/o/a/p and Hit Enter

You will get a list of files. In the list , search if anyone of the following do exist

1. Autorun.inf

2. New Folder.exe

3. Bha.vbs

4. Iexplore.vbs

5. Info.exe

6. New_Folder.exe

7. Ravmon.exe

8. RVHost.exe or any other files with .exe Extension.

If you find any one of the files above, Run the command attrib -h -r -s -a *.* and Hit Enter.
Now Delete each File using the following Command del filename (E.g del autorun.inf ).
That’s it. Now just scan your USB drive with the anti-virus you have to make sure that you made your Pen Drive free of Virus.

This virus is very common now…To know whether your system is infected just type C:\heap41a in the address bar.If there is a folder named heap41a, then your system is infected.
AVAST antivirus is the best solution for this worm.
