Computers and data have become the life line of any organization.If something goes wrong with computers or the data,business almost comes to a standstill. This causes a loss of thousands or even millions hours of hard work and research.
The full form of V I R U S is Vital Information Resources Under Seize. The essential resources of the computer like memory,processing speed,data and programs etc. cannot have normal operations and can be harmed,when virus is spread.
Virus programs are self-replicating and are continuously expanding their reach by infecting more and more computer files,resulting in loss of speed and destruction of data.
Computer programs are written to tell the computer what the user wants it to do.But Virus programs make the computer do those things which you do not want.Normally, it enters through an infected floppy or Internet/Email.
A computer virus is a program. It should not be confused with the medical term virus which is an organism.However, both of them have the same features as far as their destructive activities are concerned.Major difference between the two is that a biological virus causes physical harm to our body and attack certain cells,whereas computer virus causes harm to the data and programs stored in computer by overwriting them with garbage or erasing them.
Trojan Horses,Worms and Spyware are some other terms which are associated with virus programs but are actually different from virus programs.
