INPUT ARTICLE: Article: Windows is the most virus-prone operating system (OS) out of the three major OSes. It has the most users and the weakest built-in security. Antivirus programs will defend your computer from malware that comes through email, flash drives, downloads, websites and more. There are several popular free options available that do a good job of protecting the average user. These programs are updated frequently with new virus definitions that recognize the latest threats.  If you frequently deal with files or websites that are virus-infected, you may want to opt for more powerful paid protection. Paid antivirus programs are typically available for a yearly subscription fee. When downloading free or paid antivirus programs, ensure that you are downloading from a trusted source. There are many programs out there that claim to be antivirus/antimalware but instead install malware themselves. Read reviews and download products from companies that have been around for a long time. Windows 10 and 8 have Windows Defender, which is a free anti-malware application provided by Microsoft. It's already built-in. Make sure that no other programs are running while you install the antivirus. You will most likely need to be connected to the internet to download additional files and updates. Some free antivirus programs come packaged with toolbars for your web browser. These can add protection but also change your search options and bog down older computers. You have the opportunity to opt out of these changes during the installation process. After the installation is complete, reboot your computer and update the program. The file that you downloaded is likely not the most up to date version, so you will need to connect to your antivirus program’s servers and download the latest updates. Most antivirus programs allow you to right-click on the icon in the System Tray while it is running and click Update. Update your definitions on a weekly basis. Most antivirus programs are set to automatically update. Double check the settings for your program to ensure that you are receiving the necessary updates. Once you have the program installed and updated, it’s time to scan your computer. This could take several hours, depending on the number of files being scanned and your computer’s speed. Antivirus programs are most effective when they are automated. Open your antivirus program’s settings and look for the Schedule option. Try to schedule a time when your computer will be on but you won’t be using it. Ideally you should be scanning once a week; scan more frequently if you deal with potentially infected files on a regular basis. The best way to keep your computer protected is to always make sure that your copy of Windows is up to date. Microsoft releases security updates for Windows on a regular basis, fixing exploitable areas of Windows.

SUMMARY: Understand the need for an antivirus program. Acquire an antivirus program. Install the antivirus program. Update the program. Scan your computer. Set a scan schedule. Keep Windows updated.

INPUT ARTICLE: Article: A sapphire that has a splotchy and uneven color is not considered one of high quality.  Look for sapphires that are saturated with a single vivid color all the way through.  Avoid sapphires that have brown or gray spots within. Tone describes how light or dark a particular sapphire is.  There’s no quantifiable way to measure tone, but on a scale from light to dark, medium and dark sapphires are generally considered higher quality than those that are light. Generally, the more wrinkles and imperfections (inclusions) a sapphire contains, the less prized it will be.  To choose a quality sapphire, find one with few or no inclusions that allows you to see straight through it. The most prized sapphires are blue and come from Sri Lanka.  The second-most prized sapphire is a Padparadscha sapphire, which has a pink-orange color and also comes from Sri Lanka.  The fancy pink sapphire is the third-most sought-after sapphire.  It has a bright pink color and is generally found in Sri Lanka or Burma. Other colors like green, violet, and red are also available, but are less sought-after than the above-listed varieties. Turn the sapphire around in your hand as you hold it up to the light.  This will help you see all the internal and external elements of the gem.  Don’t rush the process.  Take all the time necessary to see all the nooks and crannies of the gem.

SUMMARY:
Look for purity of color. Select medium or dark sapphires. Pick a clear sapphire. Choose a blue, pink-orange, or bright pink sapphire. Get a good look at the sapphire.
