4 Second Opinion Anti-Malware Apps

Ransomware cyber attack

What do we mean by second opinion anti-malware?

The terms anti-malware and `anti-virus’ are the same things nowadays. Some online security companies have stayed with the ubiquitous term anti-virus, while others have reaped the benefits of using the newer term – anti-malware. The best security app to choose for your system is the one that stops the most viruses/malware. So, when an `anti-virus’ app is tested against an anti-malware app, the terms become irrelevant. It’s all about the results.

Not all anti-malware apps are designed to be standalone or full-time security apps. The apps on this page are designed to be run alongside your main security app, or occasionally – to further check your system. Hence the term – second opinion anti-malware. When you’re online, it can offer peace of mind to have this second line of defense, and it’s good to see some of these second opinion anti-malware apps occasionally blocking unwanted connections in real-time.

Here are four popular second opinion anti-malware apps.

1. Malwarebytes Premium

Malwarebytes is one of the most renowned names in anti-malware detection. We often mention it here at the computer mouse. We’ve been using their Malwarebytes Anti-Malware (Premium) for quite a few years now. It’s an anti-malware app that runs in the background and can be used alongside your main security app. It’s nice to see it blocking connections in real-time. Because of the extra added features, they say it can replace your main security app. We don’t use it as our only security app, though. We run it alongside Windows Security.

2. Norton Power Eraser

Norton Power Eraser  is one of the newer second-opinion anti-malware apps on the scene. Some of you might notice that the Norton brand logo now includes the name LifeLock instead of Symantec. Back in 2017, Symantec acquired LifeLock, Inc. Norton Power Eraser is Norton LifeLock’s second-opinion anti-malware app.

3. HitmanPro / HitmanPro.Alert

As a second opinion anti-malware app, HitmanPro is one of the most well-known. If you don’t need real-time protection, HitmanPro is an anti-malware scanner you can turn to for that last thorough PC security check. If you want always-on 24/7 real-time protection, then take a look at HitmanPro.Alert.

4. Zemana AntiMalware

Zemana AntiMalware has come a long way since it was first released. Like Malwarebytes, Zemana AntiMalware comes with real-time protection and can be run side by side with your regular main security app. It has a simple user interface, and scanning is pretty quick. When researching apps for this page, it was one of the first to block malware test files.

These are the most popular second opinion anti-malware apps for Windows. To see how many of them perform, check out The PC Security Channel on YouTube.

It’s all about the results. If your main online security app is one of the best, you might not need a second opinion anti-malware app. However, it’s nice to have a second line of defense, and it’s peace of mind to see any app at all doing a better job of improving your online security.

We use Malwarebytes Premium as a second opinion anti-malware app, alongside Windows 10’s Windows Security. We occasionally do a scan with HitmanPro, too.

Other thoughts:

Malwarebytes has a setting under Security – Windows Security Center – Always register Malwarebytes in the Windows Security Center. Some people like to toggle this setting off. This ensures that Malwarebytes doesn’t visually replace Windows Security in the Windows Security Center. It’s reassuring to see that Windows Security is the main security while knowing that Malwarebytes is working in the background.
