One of the most common way 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 portable 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.
But a special thing you want to note here is Kaspersky Antivirus is different from all of others from this.

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![]()
Don’t click 'OK' , just choose ‘Cancel’.
Open the Command Prompt by typing ‘cmd‘ in the run box.
In the command prompt type the drive letter: eg:- g:
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 it is sure that 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.

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.
