What is malware?

If you have an internet-connected device, which is almost guaranteed if you’re reading this article, then you’ll want to make sure your device is safe from malware. 

But what exactly is malware, and how can you protect your devices from it? We’ve explained everything here in this guide, so keep scrolling down for the answers. 

What is malware?

Malware (short for malicious software) is software deliberately designed to damage or disrupt computers, networks, steal data, or take control of computer hardware and networks.

If your computer is exposed to malware, it’s possible for hackers to access your private data and steal your passwords, so they’re able to access your accounts and financial information. 

There are many different types of malware, which include computer viruses, ransomware, scareware, Trojan horses, spyware and more. You don’t need to know the specifics of each type, as long as you’re aware that malware can take many forms. 

It’s easy to accidentally expose your device to malware. It’s commonly spread via email attachments or dodgy websites. That means even if you’re extra careful, it’s still possible for malware to sneak its way onto your computer. 

Protecting yourself against malware

There are a number of measures you can take to ensure it remains protected. 

We recommend keeping your devices and software updated. That includes the operating system on your computer and the firmware on your phone, but also the firmware on your TV box and router. Vulnerabilities that malware can take advantage of are usually patched promptly by their vendors, but only for versions that are still in support.

It’s also worth running appropriate antivirus software. This includes built-in security software such as Microsoft Defender on Windows and Xprotect on macOS, as well as the best third-party antivirus suites.

We think NordVPN has a really handy feature in Threat Protection, which will scan files for malware when downloading, and block you from any malicious websites. You will need to pay for NordVPN, but it’s currently available for just £2.56 a month when you apply the TrustedReviews code at checkout. This two-year plan will also bag you a VPN, password manager and lots of other security features. 

Alternatively, we recommend checking out our best antivirus and best free antivirus roundups for additional options. 

Also make sure you keep (and test!) regular backups, just in case a malware attack is more easily dealt with by reinstalling and restoring than by disinfection.
