Hi SteveQI -
I'm Kevin B., I do apologize for the inconvenience that you're experiencing right now, let me help you sort things out.
When did the issue started? Are there any changes made on the computer before the issue started?
Kindly follow the steps below to change the startup page of your browser and remove the site that it opens everytime
Open Microsoft Edge on your computer
Click on the Three dots (…) on the upper right corner of the web browser
Select Settings
On the left pane menu, click on Start, Home and New tabs
Under When Edge Starts, Select "Open the new tab page" and make sure it is selected
Under "Open these pages", check if the unnecessary site is listed
If the site is listed, Click on the three dots beside it and select Remove
Close the Microsoft Edge and relaunch it
Check if the same webpage appears
If the above method did not resolve the issue, please follow the steps below
- Reset Microsoft Edge Browser
Open the edge browser
Click on the three dots (…) on the upper right corner of the edge screen
Select Settings
On the left pane menu, click on Reset Settings
Click on Restore settings to their default values
Review the changes it makes then click Reset
You may also try to run an anti-malware scan on your computer to make sure that the computer is not infected with a malware which might started the issue on your Edge browser.
Hope this will help and have a bless day!
Thanks.
Kevin B.
