Step 3: Consider an alternative OS if Flash continues to fail

Most Windows users are unaware that software such as Flash (and WIndows) expose them to viruses, spyware and system hijacking. Because Firefox is open source, providing peace of mind you aren't being hacked, its a simple, easy first step to having a secure system, but for smart users, it doesn't stop there. Windows users should strongly consider switching to an open source Linux based system and may find that programs like Flash run better, faster and more reliably and many Linux packages allow you to keep your Windows system intact and run a dual-boot system: Windows for some aps and Linux for others. If Flash is failing in one platform, you may find it works fine in the other; typically the Linux OS. Downloading and testing/installing a Linux OS is usually free and some are easy for even novice users, and only takes a few minutes. Make sure the Linux you select has FIREFOX available or go find another one. There are over 200 varieties. Four very small, user friendly and run fast examples are Tiny Core Linux (good for Techs), Puppy Linux (good for most users), Knoppix (also good for most average users) and Pocket Rocket Linux (built around the Firefox browser - so its a good match for Firefox users). At the end of the day if you want a safe, reliable, secure system you have to rely on Firefox and other software that is open source. If you don't run a 100% open source system you are inviting problems and since the combination of Flash and Windows almost guarantees it. Here are the basics to choosing an alternative OS:

  1. Google the Linux of your choice to find their official websites. There is a big tree showing all the various distributions and evolutions at eduhosting.org - http://bigdrivehosting.com/ssl/eduhos.../linux.html
  2. Make sure you select a Linux that includes both Firefox and Flash and has a user friendly forum.
  3. Download an official version from the official site and check the MD5SUM codes to ensure your download is clean (not hacked).
  4. Here are the four Linux versions listed above, but there are many, many others.

Tiny Core Linux - http://www.tinycorelinux.com/ (less than 20MB) Puppy Linux - http://www.puppylinux.com/ (nearly 200MB depending on the version you select) Knoppix Linux - http://knoppix.net/ (more than 200MB) Pocket Rocket Linux - http://www.tinycorelinux.com/ (size varies from 20MB to 600MB depending on aps you download its very modular and is Grandmas Choice since its based on a Firefox desktop)
