Crucial Measures For Keeping Computers And Networks Secure

Whether you have a home computer or run a network of work computers, security is important. Many kinds of malicious software can plague a computer. Viruses can slow down the whole computer and use up system resources. Trojans and keyloggers can even send your passwords and account details to hackers. Some malware can even lock your entire system down and ask for payment to unlock it.

Malware is becoming more complex, so it’s important you take protection against it. Windows computers include some simple security programs, but you should look further afield to make your computer safer. Different kinds of security software can prevent different types of threats. Here are some of the security measures that can help you keep your computer safe.

Antivirus Software

The first thing you’ll want on your computer is an antivirus. Windows Defender comes pre-installed on most computers. This is considered a basic antivirus and may not be ideal for protecting against more sophisticated threats.

Anti-viruses work by searching if any malicious programs from a database are on your hard drive. You can also scan single files, multiple drives, or entire networks. You should always run a single file virus check when you download something from the internet, just to be safe.

Many free and paid antivirus programs are available. You will want one with regular updates to the database to protect you against the latest threats. Avoid any antivirus software that uses up too many system resources and slows down your computer. Look online for reviews on the best antivirus software.

Endpoint Protection Software

Even if you have an Antivirus, Endpoint Protection takes security to the next level. Endpoint security works by monitoring your entire computer, or even a network, for any suspicious behavior. By picking up on any changes, it can detect threats in advance before they become dangerous.

Antivirus software falls short in the sense that it can only detect threats on the database. By looking at the behavior of programs and connections, endpoint security can detect new and advanced threats.

This is particularly important for organizations with large networks such as businesses and schools. These kinds of networks are usually targeted with complex malware, such as the CryptoWall 3.0 Virus. Endpoint Protection Software detects and eliminates threats like this before they affect your network. This is the most thorough security solution for networks.


A firewall monitors ingoing and outgoing connections on your computer network. It can allow you to block certain threats from connecting to your computer, and vice versa. Windows Firewall is included with Windows computers, but more advanced Firewalls are also available.

Although firewalls are useful in some cases, they’re also highly problematic. Firewalls often fail by being weak enough to bypass. They can also cause issues with the internet, and falsely block programs which are perfectly safe. Endpoint Protection Software is a better solution for business networks, albeit at a higher price.

Browser Security

A simple ad blocker for your browser can protect you from many hidden threats. Some popups have built-in malware that downloads automatically. An ad blocker will prevent these threats from even showing up. It’ll also make browsing easier by blocking intrusive adverts.

The downside of ad blockers is many websites rely on advertising revenue to stay afloat. You should turn off your ad blocker on sites you trust to support them, but keep it on for sites you’ve never visited. Many modern browsers have ad blockers built in, but you can get more advanced ones as an extension.

A lot of security software also offers browser security to check sites are safe before visiting. Browsers also have many security measures. One way of eliminating possible threats is to regularly clear internet data such as cookies.

Keep Regular Backups

Keeping regular backups can help you in many cases. If a threat finds its way onto your computer, reverting your computer to a previous backup can eliminate it. It’s also useful to have backups in case of lost or deleted data. Many viruses have the potential to erase or corrupt your data.

You could use a USB stick for small hard drives, but this has some security issues. A lot of computer backup software is available for protecting computers and networks. You could also use cloud storage. It’s best to keep backups regularly; you never know when they might help.

Avoid Email Scams

Viruses and scams are often sent via email. Never open attachments from people you don’t know, and be very wary of clicking links. Never login to a website from an email link, as this can be a phishing attack. Be sure to make use of your spam filter to block email from any untrusted addresses.
