PC Maintenance and Security Lab

Which tutorial did you choose?
The labs I chose were the ones on Malware: Defining, how do you get it, an what an unprotected computer looks like.
 What was one thing you learned that you will definitely be sharing with others?
One thing I will share, especially with my teenage step-son, is that the sites that offer free movie and music downloads are the worst sites for Malware.  I did not know about P2P (peer to peer) sites...this is how college students share information, but these sites are also notorious for spreading Malware.  Another way is through IM, I had no idea that Instant Messaging could be a way to spread Malware.  I  did learn that such sites as iTunes and Napster are relatively safe ways to share things with other people and can protect you from Malware.  I would also tell people that it is important to keep up the security of your computer and always have to most up-to-date spyware as it is always changing and can break through your computer at any moment.
Was there any information that surprised you?
Some things that surprised me about these tutorials was the way a person can inadvertently get Malware and not even know it...IM and free software, who knew? I never click on a web address from a computer user I do not know...or if I do know them I can tell when the only thing in the e-mail is some strange site.  I also didn't realize that a single computer could have anywhere from 100-5,000 different Malware viruses, it just depends on how secure your computer is and how smart you are in the security of your computer.
