Antivirus Protection
A computer virus can be defined as a dangerous computer program with the characteristic feature of being able to generate copies of it and thereby spreading instantly. The viruses have the ability to modify other programs usually to the detriment of the computer system. Besides replication at an unmatched pace, some computer viruses have something else in common that is a damage routine that can deliver the virus payload. While payloads may only display messages or images, they can also destroy files, reformat your hard drive, or cause other kinds of damage which can disable your system.
The similarity of computer virus and human virus is that it spreads by inserting itself into living cells. Extending the analogy, the insertion of the virus into a program is termed infection, and the infected file (or executable code that is not part of a file) is called a host. Just like human viruses have a negative impact on the functioning of the human being by destroying the immune system similarly a computer virus destroys the operating system of the computer which can even render the computer inoperative. These harmful viruses can be easily transmitted to the computer via an attachment of e-mail, instant message or website. Another way of getting computer viruses is when we opt for free downloading without protection from a peer-to-peer connection. It is always advised not to download files before a proper scrutiny of its source and a thorough security check and regular deletion of spam mails that reduces the risk of getting infected.
