Some do it for fun, profit or to prove a point. Hacking is simple enough that a 9 year old can do it. Software Flaws / Updates Are the prime reasons computers are compromised Anti Virus Protects against viruses A virus is self replicating and tries to damage a computer Anti Malware Malware is software that’s primary purpose is not to damage a computer Malware generally tries to collect information about a user, or tries to force a user to visit sites or buy products.

Question by rdare23: Can I setup 2 print drives for the same printer on the 1 computer?
