Checking for virus in your pen drive.

Connect your pen drive or USB drive to your computer. A dialog box will pop up asking you to choose what you want Windows to do. Just click on cancel.

Go to Start- Run and type cmd to open Command Prompt. Check the drive letter of your pen drive (for example, Transcend H:).

In the Command Prompt, type h: and press Enter:

Now Type dir / w /o /a /p and hit Enter again.

You will get a list of files. See if any of these files are there:

Autorun.inf,

Autorun.ini,

New_Folder.exe,

Ravmon.exe,

MntDrCore.exe,

RVHost.exe,

or any other unknown file with a .exe extension.

If you find any of the files above,

Type the Command attrib –h –r –s –a *.* at the command prompt and press Enter.

Delete each file one by one using del file name (for example, del autorun.inf). Finally, to be sure you are free of the viruses, scan your pen drive with a good anti virus.
