How do I get rid of this obnoxious thing?

It would be helpful if you gave is some information.

A screenshot of the Avast Alert with the Details option selected would help.

Is this a site that you are actually connecting to ?
If not start by clearing your browser cache and cookies,including 3rd party cookies and restart your browser.
If that resolves it you should be good to go.
If it doesn’t try running your browser with add-ons disabled.

If that resolves it, have you added or updated any add-ons ?
If so try disabling that add-on - and restart and try again.

startseite24.net Is a browser hijacker

I would try a scan with Malwarebytes antimalware and Malwarebytes adwcleaner

Thank you, Pondus,

What Pondus says is being confirmed through this scan here:
https://quttera.com/detailed_report/startseite24.net

Two suspicious files are infested with Heur.HTML.Redirect.gen

[[]]
This is the threatdump

Also as Pondus states.
With MBAM free scan the whole computer, including memory, startup items, the registry, and the file system.
This is done so not only the residuals of Heur.JS.Redirect.gen, but also other trojan viruses hiding in the system can be detected.

Curious no one flagged Heur.HTML.Redirect.gen here: https://www.virustotal.com/gui/url/e39bb6d2f3aaecc7801b35f7cea4ee1d569dabd47ee5cb13ff8613e5bf7d16e8?nocache=1

How about that, Pondus? Are these redirects to for instance Tschibo and -bonprix.de etc, being condoned by Big Tech?

Why even Quttera mentioned site as clean on VT?

Isn’t that strange?
