Abstract:
The main functions of an anti-virus program are, (i) Virus
prevention and file protection, (ii) Virus scanning and detection, (iii)
Removing virus from infected files, and (iv) Recovering damaged files and
objects.
An anti-virus program employs various methods to detect and
remove viruses. The two popular methods of detecting viruses are signature
scanning and behavior monitoring. However each of these methods has its
strengths and weaknesses.
As the detection gets more sophisticated so are the virus
programmers. The virus programmers also try to go one step beyond the
anti-virus mechanism and create intelligent viruses which pose more and more
difficult challenges before the anti-virus producers.
