What is a Virus?
Viruses attack computers and they also have have the ability to replicate themselves, but they do damage files on Their main weakness lies in the fact that viruses can get into action only if they have the support of a host program. Otherwise, they’re just like a defeated warrior. They stick themselves to songs, videos, and executable files and travel all over the internet. ABAP.Rivpas.A, W32.Sfc!mod, are some of the examples of virus programs.

What is a Worm?
Worms are malware computer programs which have the ability to replicate themselves. Their sole objective is to increase their population and transfer themselves to another computer via the internet or through storage media. They operate like spies involved in a top-secret mission, hiding their movement from the user.
Worms don’t cause any harm to the computer; their replicating nature consumes hard drive space, thus, slowing down the machine. A couple of the infamous worms are SQL Blaster which slowed the internet for a small period and Code Red which took down almost 359,000 websites.
