Malwarebytes is a simple but effective antivirus that helps countless users get rid of pesky malware, but even it can suffer from a few issues occasionally. That leaves your device open to attacks, so you’ll want to fix the antivirus software ASAP.

If Malwarebytes refuses to open or it isn’t working how it’s supposed to, it could use a complete restart to keep fending off malicious software. Sometimes, all that’s needed is a simple update!

Having trouble getting Malwarebytes to work? This article will explain how to fix your Malwarebytes antivirus and test it to ensure it’s giving your device the proper defence.

Update your antivirus

If your Malwarebytes software is acting up, you’ll first want to check if it needs an update. Not only can this clear up any issues the AV is experiencing, but it will also help protect your device from new threats.

Antivirus software these days are efficient enough to stay updated and notify users if they require a refresh. You will usually get a notification about your software needing an update. While it can be a pain to click “Update” and restart your device for the update to take effect, it’s certainly worth doing.

While protection programs are designed to detect malware signatures automatically and use behaviour-based detection to thwart any malicious software it sniffs out, even these systems need an update from time to time. This makes sure that any new threats that have surfaced can’t get by any older systems set in place as hackers continue to find ways to sneak past a system’s protection.

All the best protection software will notify you that an update is needed if you open the app. Otherwise, you can update that software manually.

For Malwarebytes users, you can manually update by right-clicking the Malwarebytes icon in the taskbar and selecting Check for Updates. It will then scan for an protection database updates.

Test your antivirus

If Malwarebytes can’t detect or protect you from the simplest of malware, what’s the point in installing it? Well, that’s why we review different software to make sure it’s all up to scratch, but there’s another way to test if your security is working: get malware.

It’s never something you want to have on your device, but the EICAR test file will put your worries at ease. It was developed by the European Institute for Computer Antivirus Research (EICAR) to test products. And before you ask, “But isn’t using test malware still risky?” No. Not in the EICAR test file’s case.

The EICAR test file isn’t actual malware. It mimics the behaviour of malware that the security software can pick up. Providers acknowledge this as a general standard for testing, so your antivirus software will detect it like any other malware once it is detected.

So, to make sure your protection is working, try to download the EICAR test file via the website and see if Malwarebytes detects it. If it doesn’t, then you’ll want to try other means.

Upgrade your antivirus software

More likely than not, the protection software on your device is the program that came with your device when you purchased it. You may have forgotten it was there or installed free software a while back. They may not be up to standard anymore, or your device may not click with them.

Malwarebytes’ free version is fairly bare bones, as it’s more about detecting and removing malware rather than protecting you from threats trying to get on your device. Still, it doesn’t cost a dime.

Malwarebytes Premium is the company’s strongest offering. It offers 24/7 real-time protection, defends against all manner of cyberattacks like zero-day exploits and ransomware, stops brute force attacks, prevents malicious email attachments and more. It also has a flurry of scanning options, such as specific rootkit and archive scans. Moreover, Malwarebytes doesn’t increase its prices after the first year of use.
