First lets start with
Spam
Definition: Spam is another term for unsolicited commercial email (UCE). Most people with an account on the Internet are familiar with spam - it usually is advertising "spamware" (software for spammers), pornography, shady MLM (multi-level marketing) deals, and other scams. Spam was originally used to describe unwanted, off-topic, excessive posting on usenet, but has come to include email as well.
Spammer
Definition: A spammer, simply, is a person who sends spam. Usually, these are people who think that they are going to get rich on the Internet by flooding it with messages and hoping for a response. They often do get a response. However, the response is from outraged people who receive the spam and complain to the ISP of the spammer, which usually gets the spammers dial-in accounts, email addresses, and/or web pages cancelled. Instead of deleting your spam, become one of those who fight spam.
How do they get email adresses?
By people themselves
From a mailing list
Buying lists from other spammers or companies
Specialized spambots
Using spambots that scour usenet
Using spambots to scour web pages
Spambot
Defintion:A Spambot is a piece of software, a program that someone has written. Which language it was written in does not matter, but most are probably written in C for speed and portability reasons. A spambot should not be confused with regular robots, also known as spiders or web-crawlers.
A spambot starts out on a web page. It scans the page for two things: hyperlinks and email addresses. It stores the email addresses to use as targets for spam, and follows each hyperlink to a new page, starting the process all over. Spambots also usually do not follow the guidelines in the robots.txt file, like civilized robots are supposed to. Most spambots are a part of a larger program, allowing them to send out the spam to email addresses as it find them. Others merely store the email addresses for later use.
Spambots vary in their intelligence and sophistication, but even the smartest can be fairly easily fooled by the tricks on this site. The simplest spambot would simply find mailto links, and follow each hyperlink as it comes up, until it reaches a dead end. The smartest ones can recognize email addresses in many forms, recognize dead links, avoid certain types of email addresses (such as *.edu and *.gov) and track many pages at once.
Note: Do not confuse the real spamming and annoying spamming. Spamming in games or chat is when someone says something over and over again. The real spamming is when they try to sell something
That was easy to find since you can find sites with good info(Got info from

I won't go into to much detail but I'll post the 4 Viruses you'll find
Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc.
E-mail viruses - An e-mail virus moves around in e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.
Worms - A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk). Trojan horses have no way to replicate automatically.

I really see no need to go onto porn or anything
That's the info got out I'm gonna start on the research and look into WoW, CS and Guild Wars... While I'm at it anyone want me to check another game or anything?
