Some security tips

Published by:

Security is such a major issue these days, with all the spyware and malware lurking on the Internet; not to mention the nastiest viruses, worms, trojans, rootkits,  etc.

There are so many threats for our digital security. What can one do to protect themselves?

Well, there are a some things we can do as users:

  • First and foremost, develop safe browsing practices. Which means,  be mindful what websites you visit, what links you click on, what files you are downloading, and so on.
  • Next, no matter what kind of computer you have, turn on Automatic Updates for your OS ( operating system),Windows, Mac, Linux,  iOS and Android, regardless of brand or device. Android devices can get free antivirus on their smartphones and tablets from the Android Store, now called Google Play Store. Popular ones are AVG and Lookout Mobile Security.
  • Make sure you have antivirus software installed on your device and keep it up to date. Some free resources: AVG FREE , SuperAntySpyware, etc more can be found at Filehippo.com .
  • Do not open attachments in emails that have been forwarded by more than 1 or 2 people, and even then, be wary; make sure the message comes from someone you know.
  • Do not share your password with anyone, unless you know for a fact who they are.
  • Speaking of passwords, try to make them as complicated as you can, so that the bad guys have a very hard time guessing them.

These are a few of the things that come to mind when talking about security on our devices.

Use common sense, stay updated, and don’t click YES on something you don’t know what it means. Google it first or ask someone who knows.

Computers today are omnipresent, and as with any technology out there, there are also problems that need fixing.

So I want to share my experiences, and what I have learned through the years, by dealing with so many generations of Personal Computers.

That is the first lesson, a PC is any computer purchased, regardless of the brand, designed to be used in the home, office, small business, etc.

Other types: servers, mainframes, etc.

Lately though, PC has become synonymous with a Windows based machine ( Windows is an operating system created by Microsoft). Apple computers are known as Macs.

So for the sake of  convenience, we will call all Windows machines PC’s  and all Apple Computers Mac’s.

A PC/Mac is nothing more then a box of electronic circuit boards and devices, that consume electrical power when plugged in an electrical outlet.

In order for someone to make use of the computer, an operating system needs to be installed on the machine. The Operating System (OS) is a piece of software that runs in the background on your computer, allowing the user to run different pieces of software, browse the internet, check email, etc…

Most Common OS:  Microsoft Windows. Mac OS X, Linux, etc..

We will get more in depth some other time.

For now, remember: Windows XP, Vista or 7,  are the OS’s running on your PC. Same goes for MAC OS X and Mac’s.

In conclusion, in order to have a functional computer, one needs the hardware box, and the software – operating system.

That is it for the first lesson.

Let me know what your questions are, and I will reply as best I can.
