  1. 1. Robert Wayman CIS 1020-054 Internet ClassChapter 9 Digital Lifestyle: Protecting Digital Data and Devices Welcome to the digital age the most exciting time with the easy access to the internet but is it asafe place to be with all the cybercrimes taking place. Criminals are hacking into computers to stealidentities and personal info. Every day there are new viruses being made or changed and sent out toother computers. Some do little more than steal info while others can completely destroy yourcomputer. So what are computer viruses? A virus is a computer program that attaches itself to anothercomputer program (Known as the host program) and attempts to spread to other computers wheneverfiles are exchanged. Viruses normally attempt to hide within the code of a host programs to avoiddetection. With a description like that you can easily see why they call them viruses because they actjust like the viruses that a person can catch. Can you keep from ever getting a virus? Sure since a virus can only transfer from computer tocomputer by accessing a file if you never access a file with a virus you will never get a virus.But this islike living in a plastic bubble so as not to catch a virus for other people but just like people computerscan be protected and even cured from viruses with antivirus software that looks for and takes care ofviruses. Also another good way to keep other out of your computer is a Firewall with a good passwordthat is hard to figure out. So how can you tell if you might have downloaded a virus on your computer so that you knowthat you should check your antivirus software? Well first your antivirus software should be set toatomically check your computer ever couple days and should automatically update its self each day sothat it will have all the new viruses’ signatures in the library.Here some ways to know if you might have a virus but it’s not all of them: 1 Existing program icons or files suddenly disappear 2 Changes appear in your browser. If you fire up you browser and it takes you to an unusual home page. 3 Odd messages or Images are displayed on screen or strange music or sounds play 4 Data files become corrupt 5 Programs don’t work properlySo all this talk about viruses you might wonder how you can even go to web site and give them any infoabout yourself. Well it is true you should be careful about what you post expectably on site likeFacebook, YouTube and Twitter. But with a good password you can keep yourself somewhat secure butshould you use the same password for all sites? Absolutely not but then how do you keep all thosedifferent passwords in mind if you use a lot of different websites that can be a lot of differentpasswords. In both Explorer and Firefox they have password managers that you can set up to rememberthem for you and you can secure that with a Master Password. You could also get a separate passwordmanager software program to do it.
