Removing a virus without anti-virus

Virus is a computer program that can copy itself and infect computers.
The term "virus" is erroneously used to refer to other types of malware, including adware and spyware programs that do not have the reproductive ability.
A true virus can spread from one computer to another (in some form of executable code).
One of the ways by which a virus can infect your PC is through USB/Flash drives.
Common viruses such as 'Ravmon' , 'New Folder.exe', 'Orkut is banned' are spreading through USB drive .
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.So in our post we use command prompt to remove harmful files that
any anti-virus can't.


These are the steps.

Step 1:

 Run the command prompt by going to start and type cmd on the search programs and files.

Step 2:

 Select the virus affected drive

                 if there's an autorun.inf file rename it

                    (rename filename.extension newfilename )

by doing the following steps you can now acces the drive without affecting the virus
