COMPUTER VIRUS
A computer virus is a program or a set of programs that is able to copy itself and becoming a part of
another program. In addition to copying itself, a computer virus can also execute instructions that

cause harm. Computer viruses are often spread by attachments in e-mail messages or instant
messaging. That is why it is essential that you never open e-mail attachments unless you know from
whom it’s from and you are expecting it.
The full form of VIRUS 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 spreads. They are designed to spread from one computer to another
and to interfere with computer operation.
