Many users reported Unreputable browser add-ons detected errors in Avast, and today we will show you how to fix this problem.

Why am I getting Unreputable browser add-ons detected message?

As the message suggests, the reason for this error is that Avast has detected one or more problematic add-ons.

So, if you installed an add-on for your browser from an unreliable source, the antivirus identified something wrong with it.

What is the Avast browser extension?

Its complete name is Avast Online Security & Privacy and it’s a free browser add-on or extension that protects your browser.

The software can detect malicious and phishing websites; it also prevents potential intruders from accessing your data and checks your other add-ons.

If you installed this extension, there is even more reason to believe that it’s the source of this message.

Quick Tip:

In some instances, your web browser can be the cause of this problem, so you might want to replace it. Opera One is a great alternative that will automatically block ads and tracking cookies.

The browser is similar to Chrome, and since they share the same engine, Chrome extensions will work with Opera. The browser is also lightweight, and it can handle all types of multimedia with ease.

Regarding security, there’s a built-in VPN with unlimited bandwidth that should give you an extra layer of protection. Plus, this browser is smart since it comes with it’s own AI, be sure to give Opera One a try.

How can I fix the Unreputable browser add-ons detected error?

  1. Check the following locations on your drive: C:\ProgramData\AVAST Software\Avast\report or C:\Program Files\AVAST Software\Avast\x64\DATAlog
  2. Open the log file and try to find the problematic add-on.

2. Disable problematic add-ons/extensions

  1. Open your browser and check the Extensions menu. For instance, in Chrome, click the three vertical dots from the top-right corner, select More tools and then choose Extensions.
  2. Locate the problematic extensions and remove or disable them.
