Best Practices & Advice

 

The importance of backing up your data

The single most important thing that you can do with your computer system is to duplicate your important photos, music, or documents by copying them to a USB drive or USB stick. These devices are very cheap and available at computer stores, drug stores, stationary stores, Radio Shack, Costco, Walmart among others. If your read email from your browser then your email is already backed up by your service provider. Otherwise, you should backup your email data files also.

Some anti-malware programs like McAfee and Norton 360 provide backup services.

Backing up to the cloud can be useful but it might not be suitable for large amounts of data and be aware that storage rental fees may apply.

Passwords

It is often necessary today to have one or more passwords. Passwords don’t have to be difficult to use. Instead of using a word, think of a short phrase. Phrases are easier to remember than cryptic letter sequences.

For example:

Other examples:

If you have multiple passwords it is good to write them down in a notebook kept away from the computer. NEVER write them in a document stored on the computer.

5 things to do to reduce computer infections

  1. Always use an anti-virus or anti-malware program. (e.g. McAffee, Symantec, AVG, Kaspersky, ESet, etc)
  2. Never click on a link in an email from an unknown source. Even if the link is from a known source, you should be sure that the link leads to a site that you trust (or expect) by hovering the mouse over the link (without clicking) and viewing the actual link address (displayed in various ways in all browsers, usually at the bottom of the browser in the status bar). For an example, hover your mouse over the following link and look for the tip in your browser: This is a Link to this page
  3. Do not download programs from sites on the Internet other than major trusted sites. In general, it is best not to download supplemental software at all. Rather, purchase it from a reputable vendor like Amazon, Microsoft, Apple, etc.
  4. Always keep your Apple or Microsoft system updates current. Always use the latest version of your web browser and keep it up to date. Additionally, keep all Adobe programs like Reader and Flash updated.
  5. Do not use computers with older unsupported versions of Apple or Microsoft operating systems especially if you are browsing the Internet. They are much more vulnerable to infections.

The importance of a UPS (Uninterpretable Power Supply)

Weather you live in a rural or urban setting, it is always a good idea to have a UPS on your desktop computer. A power spike or outage can destroy a computer. A UPS is a plug-in wall device that provides power to your computer, conditioning the line voltage and switches to battery when the power fails. Laptops do not need UPS support as they have their own built in battery supply. A USP is quite affordable and I recommend one that can connect via USB back to the computer to inform it of power status. I like the APC brand. Some examples from APC - APC Page Here.

Tips on WiFi installations

Most WiFi routers these days have a default password. You should always change the default password on your router unless it is already unique (Some service providers like Comcast and ATT provide pre-installed unique passwords usually written on the bottom of the router). Never leave your network open with no password unless you live isolated in the country, have a great reason, or are very distant from your neighbors (greater than 300 feet away from them). It is best to always have a password.
