How to remove virus from computer without using antivirus

Computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes.

Viruses can also replicate themselves.
All computer viruses
are man-made. A simple virus that can
make a copy of itself over and over again
is relatively easy to produce. Even such
a simple virus is dangerous because it
will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.

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
