Securing Windows Devices in 2021: Top Tips & Tools

It only makes sense that there are so many threats and digital nasties designed to infiltrate and attack Microsoft’s Windows operating system (OS) — it is the world’s most popular computer platform, after all, with a conclusive market share that’s above 70 percent. Windows PCs are affordable and therefore accessible to a greater number of people. But this same accessibility makes Windows PCs a prime target.

Here we take a look at some of the threats Windows PC users face and a few ways for users to better secure their device, including native Windows tools and some third-party additions.

Three concerning threats to Windows PCs in 2021

Securing Windows Devices in 2021: Top Tips & Tools

Three pressing issues that security researchers and experts have flagged in 2021 include:

Emotet Trojan

Since it was first identified in 2014, the Emotet Trojan has been kept updated by threat actors, and as such, it continues its reign as a leading malware threat in 2021. This is despite concerted efforts by law enforcement agencies to halt its spread.

As Maya Horowitz, the director of Threat Intelligence and Research at Check Point, puts it: “Emotet is one of the most costly and destructive malware variants ever seen, so the joint effort made by law enforcement agencies to take it down was essential, and a huge achievement.”

The takedown led to a 14 percent decrease in enterprises attacked by the Trojan, but even so, it holds a top position in the Global Threat Index. Emotet is present in fake Windows updates, which appear on the user’s screen.

Clop ransomware

Nimble and agile, the Clop ransomware program can kill a multitude of Windows 10 and Microsoft Office applications. It’s perhaps best known as the digital nasty that encrypted nearly all of the Windows systems at Maastricht University in 2019.

Now, in 2021, Clop is evolving and becoming more aggressive; it is now capable of shutting down 663 Windows processes, including Defender, and infiltrating entire networks. While Clop is arguably more of a threat to enterprises running whole networks of Windows PCs, individual users have also been targeted.

Pandemic-inspired social engineering attacks

The Financial Times called COVID-19 “a gift to cybercriminals” and indeed, it seems the pandemic has proven to be a fertile ground for any number of coronavirus-related scams, misinformation tactics, and malware.

More often than not, these attacks are delivered via social engineering tactics designed to trick users into opening an infected link or handing over sensitive personal and/or financial data. From phishing emails offering vaccines to malicious advertisements, there are so many pandemic-inspired threats that detailing them all is next to impossible.

And as there are so many Windows users, the vast majority of these digital nasties are quite capable of entering Windows PCs with ease.

How to better secure your Windows PC

Secure Windows 10 Devices Tips

Boost your PC’s cybersecurity credentials with the following tips and tools:

Native Windows tools

Windows 10 offers some of Microsoft’s best in-built tools thus far. Taking advantage of these native solutions can help protect your PC. Let’s take a look at some of the key safety features in the OS.

  • Windows Update — Automatically protect your PC by ensuring it is running with the latest patches and bug fixes installed. As tedious as Windows updates may be, they are essential when it comes to keeping threats at bay. If you’re a Windows 10 user, updates happen automatically. For users of older OSs, periodically check for updates and install when one is available. Note that Windows Update does not mean third-party apps are updated, so keep this current separately.
  • Windows Defender — While it may lack the advanced threat detection skills of third-party software solutions, Windows’ own antivirus, antimalware, and firewall solution should be in use if you’re not using other tools.
  • Bitlocker — Available for Enterprise and Pro Windows 10 users, Bitlocker offers an advanced disk encryption tool.
  • Windows Smart Screen — With Smart Screen enabled, your device will automatically steer you away from infected websites and pages that contain malware when you’re using Edge.

Third-party tools

In addition to the above, consider using the following for extra layers of security:

  • Virtual Private Network (VPN) — Using a VPN for PC security is always a wise move as a VPN encrypts all of your traffic, making it near impossible for threat actors to detect.
  • Antivirus & Antimalware — As mentioned above, Defender does lack when compared to third-party solutions, so if you can, invest in high-quality, paid antivirus and antimalware solutions.
  • Password manager — All too often, users rely on the same password, not easily crackable passwords. A strong password manager or password-protect application can help you keep your accounts more secure and save you the hassle of trying to remember long, complex passwords, making it much easier to keep your security duck in order.

While Windows might be a target for threats of all kinds, there’s no need to sit back and expect a digital security issue. Make the most of Windows’ in-built, native tools and invest in some quality third-party security tools to boost your device’s and your data’s security.
