Some Steps to Secure Your Computer

For the average user, taking several basic measures should be sufficient enough secure your computer and its contents. In this post, we’ll outline eight easy steps you might want to consider. While they’re all fairly straightforward to implement, some take a bit more time than others or involve paid options. As such, you might need to weigh up which solutions are necessary in your situation. Let’s jump in!

1. Keep up with system and software security updates

While software and security updates can often seem like an annoyance, it really is important to stay on top of them. Aside from adding extra features, they often cover security holes. This means the provider of the operating system (OS) or software has found vulnerabilities which give hackers the opportunity to compromise the program or even your entire computer.

Typically if an update is available for your OS, you’ll get a notification. You can often opt to update immediately or set it to run at a later time. While it can be inconvenient to stop what you’re doing for half an hour for an update to take place, it’s often best to just get it done out of the way.

It’s not just your OS that should be kept up-to-date. All software that you run on your computer could potentially have flaws. When updates are available, you might see a popup when you open the software.

Even though they are usually a good thing, it’s prudent to be wary of updates. Sometimes software companies will offer pre-release versions to try. These may be unstable and should be used at your own risk. Even with stable release versions, you may want to wait a day or two in case there are any obvious bugs. Just remember to go back to it when you’re ready.

Another thing to watch out for is a fake update. These might be used by hackers to persuade you to click a link or enter credentials. You can avoid falling prey to these by doing a little research into the latest updates from the software company. Simply search for the latest version to see if the alert you received makes sense. Alternatively, you can plug the popup text in a search engine to find out if it’s a known scam.

2. Have your wits about you

It should go without saying, being suspicious is one of the best things you can do to keep your computer secure. Admittedly, with hacker techniques becoming increasingly sophisticated, it can be difficult to tell when you’re under attack. All it takes is one email open or link click and your computer could be compromised.

Make sure you have your wits about you and think twice about opening or clicking on anything that doesn’t look legit. Don’t rely on spam filters to always catch sketchy emails. Criminals are constantly trying to outsmart these settings and now and again they’ll get through.

3. Enable a firewall

A firewall acts as a barrier between your computer or network and the internet. It effectively closes the computer ports that prevent communication with your device. This protects your computer by stopping threats from entering the system and spreading between devices. It can also help prevent your data leaving your computer.

If your computer ports are open, anything coming into them could be processed. This is bad if it’s a malicious program sent by a hacker. While it’s possible to close ports manually, a firewall acts as a simple defence to close all ports. The firewall will open the ports only to trusted applications and external devices on an as needed basis.

If your operating system comes with a firewall (e.g. Windows XP onward), you can simply enable the built-in firewall. In Windows, this can be found by navigating to Control Panel>System and Security. You might choose to install an additional firewall as an extra layer of defense or if your OS doesn’t already have one. A couple of free options are Comodo and TinyWall. Antivirus software often comes with a built-in firewall too.

The firewalls discussed above are software firewalls. There is a second type known as a hardware firewall. While these can be purchased separately, they often come built into home routers. It could just be a simple case of checking if yours is turned on.

4. Adjust your browser settings

Most browsers have options that enable you to adjust the level of privacy and security while you browse. These can help lower the risk of malware infections reaching your computer and malicious hackers attacking your device. Some browsers even enable you to tell websites not to track your movements by blocking cookies.

However, many of the options are disabled by default, so you could unwittingly be exposing far more than you need to each time you browse. Thankfully, it should only take a few minutes to go into your browser settings and make the necessary adjustments. Chrome, Firefox, Safari, and Edge all provide detailed instructions to help. While using these browsers you can add an additional layer of protection by installing an anti-tracking browser extension like Disconnect or uBlock Origin.

On the topic of browsers, you should choose yours carefully. The ones mentioned above are generally considered safe. But since updates and patches occur all the time, you never know when a new hole could appear and how big it will be. If you want more privacy, you can consider steering away from traditional options and look at privacy-focused alternatives like Epic Privacy Browser, Comodo Dragon, or Tor Browser.

5. Install antivirus and anti spyware software

Any machine connected to the internet is inherently vulnerable to viruses and other threats, including malware, ransomware, and Trojan attacks. An antivirus software isn’t a completely foolproof option but it can definitely help. There are free options out there, but they’re limited, and besides, the paid programs won’t set you back a whole lot. Bitdefender, is a popular option that I recommend. For alternatives take a look at this data backed comparison of antivirus.

Spyware is a specific type of malware that is designed to secretly infect a computer. It then sits in the system, gathers information, and sends it to a third party. The information is typically of a sensitive nature, such as credentials or banking information. This can ultimately lead to identity theft, a multi-billion dollar industry.

In the spyware category, you have adware (often causing popups), Trojans (posing as a harmless software), and system monitors (such as keyloggers), all of which pose a pretty serious threat. Other forms of spyware like tracking cookies are typically harmless alebit annoying. Thankfully, many antivirus programs have anti spyware built in, but there are some dedicated solutions.

If spyware has found its way onto your computer, then it’s very possible you can remove it. There are a ton of options for spyware removal, including many free offerings and some paid single use tools.
