What is Computer Virus ?


A computer virus is a type of unwanted computer program which is developed by miscreants with an intention to infect the files of a computer, to corrupt a database or to hamper the functioning of a computer system.

In a computer system, virus does not evolve by itself, it is uploaded in a network or into a storage media. It is communicable i.e. it is transmitted form one computer to another computer or to a network by some medium of transmission like CDs, pen drive, external hard disk, softwares, internet connection, bluetooth, etc. When infected, many viruses replicate by themselves. 

There are different types of viruses that infect specific components or specific functioning of a computer system. They can range in severity. Some may cause mild damages while others can severely damage hardware, software or files. Example of some common viruses are iBryte, OneInstaller, Koobface, BrO_AcT, Byte Bandit, Brain, Small.TP, Stealth_C, etc.
