Malware
Harmful Software
What is Malware?
Malware is software (Like safari, internet explorer, etc. Stuff on your computer) that is intended to upload viruses. Viruses are programs that copies itself and also needs contact to spread.
Types of Malware
Malware comes in many forms: Viruses (described in "What is Malware"), Trojan Horses, and Spyware. I'm sure you've heard of how the Greeks defeated their opponents. This is the same concept, only it is malware that opens the "doors" for the hacker, etc.
Spyware is a program that secretly sends your info back to the hacker and this program sends it off so secretly you don't even know it's happening.
How to prevent this
There are two major ways to stop this crime.
Antivirus software is helpful because the program has a list of programs that are bad and it checks this list every time you go onto a website.
Firewalls are also helpful because when the web is trying to access you computer, or vice-versa, this firewall asks your permission.
