Though viruses are mushrooming at a faster rate than
vaccines still there are very good and reasonable anti-virus
software to assist its users to keep their computer
system virus free. At present, the following are the
most popular anti virus software:
Norton anti virus

The function of anti-virus software is to
perform one or more of the following functions:
Prevention :
Anti-virus programs may be preventive or restorative.
Preventive techniques include stopping attempts at
direct access such as formatting and deleting, or
even write protecting the hard disk while testing
familiar software. The restorative process is achieved
by maintaining a copy of CMOS information, boot sector
information, the file allocation table, etc., in a
safe area like a floppy.
Detection :
The detectors warm the user of the presence of a virus
after it is loaded into the machine or disk. These
programs maintain a file with a list of checksum values
of the executable files. The identifiers rely on the
fact that when the replicates, it makes a copy of
itself.
Vaccination :
The vaccinators inject some code into the executable
files. When the vaccinated file is run, the injected
code performs an integrity check on the program being
executed and warns if any changes have been made.
Inoculation :
The inoculators insert the virus signature into infected
areas or files at appropriate location. When the virus
performs their self detection, they find their signature
and believe that the memory/disk/file is already infected
and so do not infect.
Damage control :
The better equipped anti-viral programs are also capable
of controlling damages caused due to virus attack.
