Describe Different Types of Viruses.

Computer Virus:

A computer virus is a parasitic program that infects other legitimate programs, which are sometime referred as hosts. To infect the host program, the virus modifies the host to store a copy of the virus. After infection, viruses make various damages to the system which may be low to high to critical.

To qualify as virus, a program must be able to replicate itself. This can mean copying itself in different places on the same computer or other computers by reaching them using connected networks or internet.


Taking control of hardware devices, slowing down computer by taking control of resources, filling up storage space, making files & folders inaccessible etc are a few among various activities of computer viruses.
