Wow, there are way to many to list, so no thanks.
1.Worms have a slow affect on your computer, they corrupt and delete your data.

2.Spyware is a live and controlled virus by which someone can access the data on your computer and alter data and memory in your computer.

3.Trojans are found in downloaded files such as music, movie or software files. These evolve into worms over a period of time (can be weeks or days) and contaminates computer files

All of these types of viruses are received through the internet and can be cleaned through anti-virus and spyware programs.

Spyware -- Ad-aware, Spybot

Anti-Virus -- AVG, Mcafee
they send out personal info/preferences to websites (usually inappropriate websites)

We don't have enough time or space to explain each and there context as to wht they do.

There are literaly hundreds of different bad things and each can affect different things in different ways and none are really standard in what they can and will do.

I suggest you use this link and type in each one you have questions about and you will see why I said we don't have time or space.
