Keep getting Dangerous Webpage warning when using Chrome

Avast Free Antivirus / Premium Security
1

When I open a new tab on Chrome I get the following:

“We prevented your connection to secdomcheck.online because it is a dangerous webpage. Threat category: URL:Blacklist

46d1a2d14fe6/2026-02-15T20:17:35.747Z "

What can I do to get rid of this threat?

First, I’m an Avast user and not an Avast Team member.
Note I don’t use Chrome or Avast Secure Browser (which is based on chromium code).

Lots of related hits on a google search.

Are you actually trying to connect to this site (I suspect not) ?
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.

If still not resolved and you are using Chrome based browser - try this suggestion by Avast Team member ‘lukor’ - What about page notifications?

  • Here: chrome://settings/content/notifications ?
  • Do you have all cleared?
