To clean infected pen drive

MntDCore.exe, Ravon.exe and Ravmon.exe are the most common pen drive viruses. Along with these you will find Autorun.inf and autorun.ini in your pen drive. Autorun.inf and autorun.ini direct the pen drive to the virus, wreaking havoc on your system. Some viruses like Ravmon and Heap41a worm cannot even be detected by some anti virus software and spread rapidly through pen drives from one computer to another. You can protect your PC by following some simple steps.

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, NewFolder.exe, Bha.vbs, Iexplore.vbs, Info.exe, New_Folder.exe, Ravmon.exe, Ravon.exe, MntDrCore.exe, RVHost.exe or any other file with a .exe extension.

If you find any of the files above, Run the command attrib –h –r –s –a *.* at the Command prompt and press Enter. Delete each file one by one using del filename (for example, del autorun.inf). Finally, to be sure you are free of viruses, scan your pen drive with a good anti virus.

Currently, the Heap41a virus is spreading fast. Check your drives to see if there is a folder with this name.
