Before discussing further topics on viruses and their removal let’s first have a look at the differences between viruses, worms and Trojan horses. For sure, these are some malicious programs that can cause damage to our computer and the data stored on it.
What is a virus?
Virus is some computer code written in some language and can spread from one system to another on its own. It can also replicate on its own and poses threat to hardware, software and the data stored. But if you also wished to make your own virus then read this post of mine.
What is a worm?
A worm is just another class of virus and is capable to replicating on its own automatically. They can replicate in large volumes and do not really need any user action to replicate. They can just send out their copies to other computers which can further send out theirs. A worm can consume memory which can cause a computer to crash.
What is a Trojan horse?
Trojan horse is a computer program that is harmful to computer but may appear to be useful. Trojan horses spread when we open some thing that comes from a non trusted source. It is therefore also advisable to not to download anything from the same illegal site.
Always have some good Anti Virus installed in the system for the added protection.
