Why does my browser keep opening multiple windows?

This is not at all a good sign, and you should consider taking immediate safety measures. Know that browsers opening multiple tabs automatically is often due to malware or adware.

How do I stop multiple windows from opening in the browser?

1. Switch to a new browser

Aren’t you tired of the same old browsers? Here’s our recommendation. Use a browser that has been around for a long time, so that you benefit from all the experience over the years. The same one should have been redesigned and reborn, completely modern.

Don’t have one in mind? We do. It’s called the Opera browser. It’s based on the Chromium engine, with multiple personalization options and a lot of features that are quite useful while browsing.

For instance, you might have a lot of tabs opened. You can perform a search through all your open tabs.

Another scenario is that you encounter geo-restricted content while browsing. With Opera, which comes with a built-in VPN, you can quickly enable it and get past the restriction easily.

How about increasing your productivity? Things such as My Flow and Workspaces have been designed specifically to help with many opened tabs and repetitive actions.

How do I know if my computer has malware?

Just like with a disease, there are certain symptoms that indicate a malware infection. First of all, your system will be significantly slower than usual.

Besides the fact that your screen will be full of useless and annoying ads, your system will constantly crash, you will always be low on disk space, and the browser’s settings will change.

Furthermore, your trusty antivirus software will stop working, giving you a false sense of security, and you will also lose access to files on your system.

There are other signs that could indicate the same thing as well, but these are the most obvious ones and you should prioritize dealing with the situation if you observe this.

Millions of people worldwide are dealing with dire situations where their data has been compromised, leading to loss of files, money, even identity theft, and much worse.

So, if you see your Chrome opening multiple tabs, or any other browser performing actions that lead to multiple windows opening uncontrollably, stop what you’re doing and eliminate the threat.

As we said, a browser opening multiple tabs is never a good sign and is by no means a mistake. It’s the number one sign that your system has been compromised.
