What did we learn so far?

We learned already:

  • We need an antivirus and a firewall. This is the absolute minimum for any computer!
  • Internet (the virtual world) is exactly the same as the real world. There are bad and good guys. We need to protect us and the community against the bad guys!
  • Any computer with Windows, Mac and Linux Operating Systems and…, are vulnerable!

              • Windows updates and updates for Mac and Linux must be made as soon as they are available! Any other installed program on the computer must also be updates asap!
              • There are FREE antivirus programs and commercial antivirus programs. We learned also the difference between those two variants.
              • We learned that there are better protections, such as “Internet Security Suites”!
              • We learned that ALL “Browsers” need to be secure also!

    Hello Gustmeesen,
    I know what you mean, When it arrives to securing a personal computer network, most women and men only believe of firewall. Well firewall is a relatively essential component of home computer networking. It can be the front line of laptop networking safety. But you’ll find it only the number one step and there is a single added lacking piece of the puzzle.
    Keep up the posts!
