The Problem Explained

Most computer users hope for a smooth and quick boot when they turn on their PC. However, having many programs enabled on startup can slow things down significantly.

Despite Avast’s Secure Browser being helpful where privacy is concerned, many users have complained that the software is more intrusive than they would like.

This is a significant concern among members of the community and a leading reason that Avast is often uninstalled and abandoned by its users.

We can’t support such intrusiveness under any circumstances, especially when it comes from a company apparently dedicated to security and trust. At the same time, this problem is easy to solve.

Only you can decide whether or not this is a deal-breaker, but we’re here to show you the solutions. Let’s get into it.

Fix 1: Disable The “On Startup” Option In The Browser Settings

Like most similar software, the Avast Secure Browser features a Settings panel where you can enable or disable features to customize your experience.

By default, the “On Startup” setting is configured to be on. You can disable this by turning it off with one click.

Disabling Avast Secure Browser auto launch

The Avast Secure Browser has a very similar interface to the one used by Chrome, so you shouldn’t have too much trouble figuring out how to enable and disable certain features.  

After disabling the setting, as shown in the image above, the browser should no longer open on startup. You can also disable the feature below it in the menu, which will prevent the browser from checking if it is your default one on startup.

Fix 2: Disable Avast Secure Browser From Task Manager

If the previous method doesn’t help, which is rare but has been reported by users in the past, the next reliable solution is disabling the browser in Task Manager.

This is straightforward, but if you are unsure how to do it, you can follow the steps below:

  1. Right-click the empty space on your taskbar and select Task Manager in the menu. Make sure you don’t right-click the icon of a program. See the image below for further guidance.

Close Task Manager and reboot your PC. The browser should no longer start automatically when your system boots up.


You now know how to deal with the Avast Browser opening on startup problem using the easy-to-follow methods listed in this guide.

Unfortunately, this feature has driven many people to stop using and supporting the company, switching to a different antivirus provider, likely because they couldn’t find a way to disable it without a complete uninstall.

If you encounter any further problems, consider contacting Avast’s support team.
