If your laptop’s internet browser is opening multiple tabs or windows on its own, it is likely due to a virus, malicious software, or an improperly configured browser or add-on. To fix the issue, try the following steps:

1. Check for anti-virus or anti-malware software on your laptop and make sure it is up-to-date
2. Scan your computer to detect any malicious actions taken by a browser hijacker
3. Run a system scan using your browser’s security settings to detect and remove bugs
4. Delete any unauthorized browser extensions or add-ons, and reset your browser settings to default
5. Make sure your browser is up-to-date and running the latest version
