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 …

An anti-virus program typically employs various strategies to detect and remove viruses. The popular methods of detecting virus are signature scanning, heuristic scanning and integrity checking. However each of these methods has its own strengths and weaknesses.
Signature scanning (or searching of known virus patterns) is the most common method of virus detection. But it cannot detect viruses whose signatures are not available in the virus database. The other popular method is to use a heuristic algorithm to find viruses based on common behaviors. This method can be complex, but it has the ability to detect unknown or new viruses. …
