This updated 2017 guide about computer and online security covers the topic in more modern detail than many of the points below: The jargon-free guide to computer and internet security
If you are using Windows, then you should be familiar with Internet Explorer (the blue e) as the built-in program for viewing web pages (web browser). If you are using a Mac, then Safari would be the default program on this platform. Both Internet Explorer and Safari are not recommended for browsing web pages on the Internet. The previous versions of Internet Explorer (version 8 and below) lack the ability to display some parts of web pages, so you are actually missing some content if you are using Internet Explorer. Safari has been proven to be highly exploitable, where in the last few years it has been the first to go down in a hacking contest (pwn2own), sometimes within seconds. Firefox and Chrome are the recommended browsers for both Windows and Mac to see web pages are they intended to be displayed, with Firefox as the more popular choice. Internet Explorer 9 was released in March of 2011 and helped to fix many of the shortcomings known with the previous versions.
Webmail is handy if you need to access your email while away from your home computer, but it is not a replacement from using a proper email program to check and manage your email. Many people may end up using the webmail from the website because it requires no setup and is easy, but this lacks key features like message filtering and offline access. With an email program like Thunderbird or Windows Live Mail, you can setup filters to handle the messages as they come in, this means that the program will help you to automatically move spam messages and other junk as it comes in. Another benefit of checking your email with a program, is that the messages are stored on your computer, so you will still have access to them, even if you do not have an Internet connection. If you would still like to be able to use the webmail when away from your computer, then set the email program up with the incoming server type as IMAP (instead of the default POP type) so that a copy of the messages is left both on your computer as well as on the mail server (webmail), just be mindful that the mail server does not allow you an unlimited amount of storage. Please read the section below about antivirus programs, as many of them create problem with email access.
Considering the way that many antivirus programs severely slow down your machine, break your email and Internet, corrupt your files, and ask you for your money at the same time, they are not too much different from having an infection on your machine. For Windows users, Windows Defender is built-in and it's free. Don't be fooled by the marketing campaigns of the other antivirus providers, they leverage your fears for your dollars, and tout unnecessary features like software 'firewalls', email scanning, and some bunk about scanning for safe web links. For a real firewall, NAT translation is recommended, which is provided by every router (except the factory configuration of some Apple routers), and is also provided through the MCSnet radio if you do not have a router to do this (if you have a router, NAT is off on the radio we install on your roof, and if you have no router, then NAT is on). Email scanning is an unnecessary addition, and just another point of failure - a proper antivirus is scanning everything on your computer already, there is no need for a redundant check on your email, it is already being scanned by the real time scanner. Most antivirus programs like Norton and Mcafee are force fed to you as you purchase your computer, remember that you should only have one antivirus program installed at a time, if you completely uninstall your current antivirus program in Windows, Windows Defender should take over automatically. If you have a Mac, then Apple has been recommending the use of an antivirus program for a couple of years now, unfortunately, none of the current solutions are very nice, but not using Safari is your best first step.
Although wireless connections can be very handy, they also introduce unnecessary complications and additional points of failure between your computer and the Internet. Instead of relying upon a wireless connection between your computer and wireless router, use a cable where possible. A cable requires no configuration, just works, and is faster. Wireless networking has improved as the technology and standards improve and adapt, but who wants their Internet connection to go down every time someone turns on the microwave or pop-corn popper?
The first few tips here are to keep your system, programs, and antivirus up to date, and then we explore some common sense for email and the web. The common sense section is the most important; although antivirus is recommended, with proper habits, you should be able to safely surf without using any antivirus at all. Most infections are applications that are socially engineered to trick you into installing them, and they are not getting onto your system without your co-operation.
#1 – Install Operating System Security Updates
Whether you are using Windows, Mac, or Linux, every operating system has bugs and security exploits. It is critical to keep your system up to date by installing security updates as they are released. Windows users should automatically receive updates on the second Tuesday of every month, or you can manually check for updates through Windows Update. If you are using Mac or Linux, you might think that this does not apply to you, but there are a large number of critical updates released for both platforms regularly, and Apple has been recommending that it's users install an antivirus for the past couple of years.
#2 – Install Application Security Updates
Just as in suggestion #1 above, there are bugs and exploits in most of the programs that you install on your computer, and it is common for the black hats to go after software that is likely to be installed on most machines, like Adobe Reader/Flash, Java, Internet Explorer, and itunes/Safari. Installing the newest version of the software is the best way to keep these up to date.
#3 – Install a quality Anti-Virus Application
We are lucky to have Microsoft Security Essentials available, it's the best antivirus on the market, and it's free. Remember to remove your current antivirus program before installing a new one. If you are on a Mac, then Security Essentials is not available to you, so you might want to do a bit of research to see what is going to work for you. Windows 10 has Security Essentials built in, under the newer moniker Windows Defender.
#4 – Keep your Anti-Virus up to date
New viruses and vulnerabilities are found daily around the Internet, and the definitions to antivirus are often updated daily to catch the associated attacks. If you are using Microsoft Security Essentials, then definitions are updated daily, but your computer should get these automatically through Windows Update.
#5 – Using your Brain to Outsmart Common Scams and Tricks
This is the most important section as far as security is concerned, as nearly all infections require your co-operation to get implanted in your system.
