ABSTRACT
Viruses: A virus is basically an executable file which is designed such
that first of all it should be able to infect documents, then it has to
have the ability to survive by replicating itself and then it should
also be able to avoid detection.
Computer viruses can be classified into several different types.
File or program viruses: They infect program files like files
with extensions like .EXE, .COM, .BIN, .DRV and .SYS. Some file viruses

Do viruses and all the other nasties in cyberspace matter Do they really do much harm Imagine that no one has updated your anti-virus software for a few months. When they do, you find that your accounts spreadsheets are infected with a new virus that changes figures at random. Naturally you keep backups. But you might have been backing up infected files for months. How do you know which figures to trust Now imagine that a new email virus has been released. Your company is receiving so many emails that you d ....etc

A computer virus is a self-replicating program containing code that explicitly copies itself and that can infect other programs by modifying them or their environment such that a call to an infected program implies a call to a possibly evolved copy of the virus.

These software pranks are very serious; they are spreading faster than they are being stopped, and even the least harmful of viruses could be life-threatening. For example, in the context of a hospital life-support system, a virus that simply stops a computer and displays a mes ....etc
