Any Malicious Software

What they "look" like

Viruses- copies itself; needs contact to spread

It can be over the interent and do whatever the programmer wants it to do (for example: delete system files to make computer not work the way its supposed to)

Trojan Horses: Seem legit but allows access to someone else

Think you are downloading something and something else comes with it

Spyware- Secretly obtains personal information

Can be used for marketing or things like bank account passwords or information used to steal your identity

Avoid Being a Victim

Install an AntiVirus Software on your computer, a Firewall, and most importantly, use your common sense!
