If you’re experiencing issues with your browser or Internet connection, you may need to restore your browser or Internet connection manually. To help resolve browser or Internet connection issues, see the suggestions below.
Restore browser preferences
Browser is slow or unresponsive
A browser is responsible for running many utilities, including extensions, add-ons, notifications, and multiple tabs. When a browser runs utilities, this can cause the browser to become slow or unresponsive.

Browser settings changed
If you see an unfamiliar website, search box, or advertisement when you open your browser, it’s possible your browser preferences were changed. Malware, adware, extensions, and other downloaded content can change the homepage, search engine, and other preferences you have set in your browser.
To restore your browser preferences, refer to the following articles:
- Apple Safari:
- Google Chrome:
- Mozilla Firefox:
Receiving unwanted advertisements

You can allow certain websites to send notifications to your computer.

If you are seeing advertisements, it’s possible notifications were enabled for a specific website.

- Apple Safari: Notifications preferences in Safari
- Google Chrome: Block or allow pop-ups in Chrome
- Mozilla Firefox: Web Push notifications in Firefox
Problems on a specific website
If you’re unable to connect to a specific website, there’s a chance the issue exists on the website itself and not on your computer. You may want to avoid using the website or report the issue.

Internet connection is unsafe
A DNS server is responsible for translating a website address into an IP address. Hackers can compromise DNS, causing the server to take you to an unsafe website. If your browser’s Internet connection is unsafe or you are being directed to unfamiliar websites, contact your Internet Service Provider (ISP) for further assistance.
Same issue on multiple devices
Malware can cause multiple devices on your network to experience the same issue, such as:
- pop-up advertisements
- unsecure websites or warnings that your connection is not private
- lost Internet connection
If you have more than one device showing the symptoms above, it’s possible your network hardware is compromised. To troubleshoot issues with your network hardware, refer to the article Malwarebytes has not detected or blocked malware, or contact your Internet Service Provider (ISP) for assistance.
