Malware

Viruses - Lysol wipes aren't going to help you here. Computer viruses can be transmitted between connected devices much like the way viruses are spread between people. The objective of the virus can range from destroying your system to giving cyber-criminals access to any infected devices. 


Spyware - This type of intrusive malware generally is used to track your activity on the infected system. It can download itself without permission, open annoying advertisements, and steal your passwords.


Botnets - Bot, James Bot 001... Networks of computers under the malicious control of criminal puppeteers. Like puppets, these systems are controlled by a remote hand that give commands to carry out specific instructions (command and control). 


Ransomware = digital kidnapping. Essentially, this malware will encrypt ALL data on your computer and demand some form of payment to get it back.
