Every living being have got one or other kind of virus and have suffered through the infections like common cold and flu. It attacks through entering the human body and attaching it self to host cell. It causes the disease in the cell body by introducing a piece of genetic code in to the cell and recruits the enzyme of cell to propagate that code. It keeps on moving to other cells as soon as it destroys a host cell.
But the question is how this biological piece of virus gets in to the computer system. Actually it is something of technical nature say, software which works similarly as a biological virus does. It works by placing its execution code in the path of other programs execution code. A computer virus is responsible for interfering with proper functioning of the computer. It may end up damaging your programs, deleting files and reformatting disk drives.
Software can be classified as “virus” must have two things in it.
- Must be able to execute it.
- And it must be able to replicate itself.
Viruses are notorious for the way they are damaging the computer world and propagating for more damages. However another tool for destruction has gained much popularity and is known as “WROM”. It is now creeping all around the network. We are all much aware about and do feel frightened of a Blaster worm which generally attacks, Microsoft websites. But what a worm is? Actually it is a sort of virus software which has different way of attacking the system. It does not require a host program to propagate through. It enters through a weakening hole in the computer system and starts propagating.
A typical virus requires activation while worm is activated on its own. But for both preventive measures are same. Buy antivirus software or get your virus scanned online for spyware, malware, worms and viruses.
