Malware
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!
