One of the best free antivirus software to get is Avast One, as the redesigned security package comes with a plethora of tools to keep your device safe from malware. That is if it’s working.

Whether the antivirus needs a simple update or a complete reinstall, there are several ways to fix any problems Avast One is having on your device.

This article will help you figure out how to fix Avast One and the best way to test your antivirus to see if it’s actually doing its job.

Update your antivirus

Avast One may be having trouble because the program or virus database aren’t up to date. The good news is you can manually install these updates in a few clicks.

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.

In Avast One’s case, you can manually update its virus definitions database (used to identify known malware threats) and the applications. Right-click the Avast One icon in the notification area of the taskbar and click Update. From there, you can click Engines and virus definitions or Program.

If the update doesn’t run automatically, click Check for updates.

Test your antivirus

If Avast One 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 Avast One 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.

If that’s the case, consider upgrading your Avast One subscription package. While Avast One Essential is a great offering seeing as its completely free, the Avast One Individual subscription is a step up. It offers protection for five devices, more online privacy tools like a webcam safeguard and online banking protection, an unlimited VPN (55 locations, 34 countries), more optimization tools, and a few extra security features.

There’s also Avast One Family, which comes with the same features as the Individual package but lets you protect up to 30 devices. This is more for families with a lot of devices or small companies looking for malware protection.
