A computer virus bonds itself to a file so that it can corrupt computer and spread to other computers as well. The viruses are attached to an executable file and they infect your computer when you run or open that malicious program, so a virus cannot be spread without a human action. It generally spreads by sharing infecting files or sending e-mails with virus attachments unknowingly to the user.

A computer worm is a self-replicating computer program. It has the capability to travel without any help from a person. A worm uses file transport features on your system and thus spreads throughout computer by replicating itself.
Worms harm the system by spreading replication and consuming bandwidth whereas viruses corrupt files of computer. So a computer worm differs from a computer virus in that a computer worm can run itself. Worms generally enter a computer through an e-mail.

Computer worms can be taken care of by keeping up-to-date in installing patches provided by operating system and application vendors whereas viruses can be given a check by using antivirus software, which detect some of the worms even.

A computer virus is a small program written to alter the way a computer operates, without the permission or knowledge of the user. A virus must meet two criteria:


It must execute itself. It often places its own code in the path of execution of another program.
It must replicate itself. For example, it may replace other executable files with a copy of the virus infected file. Viruses can infect desktop computers and network servers alike.
Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply to replicate themselves and make their presence known by presenting text, video, and audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by legitimate programs. As a result, they often cause erratic behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.
