What is A Computer Virus?
A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware, including but not limited to adware and spyware programs that do not have the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive.
How May A Virus Spread?
A Computer Virus Can Spread By Many Ways. We Use Internet, Share Our Files by Using Pen-Drives, CD, DVD, Download Files. There Are A Lot Of Ways For A Virus To Get Spread. So You Can’t Say That “I Am OK”.
