avast keeps popping up phishing threat secured

Yesterday I opened a PDF file with Microsoft edge (the file is confirmed safe it’s a scan that I made myself) and since then avast went bonkers, it keeps reporting phishing threats blocked, from all the browsers, (never used edge for browsing but it nags me that when I open it goes mad), Svchost2, and sometimes firefox, but a lot less, and all the times the weird blocked site is different.
I ran a complete scan, with malwarebytes too, cleaned the cache of all the browsers, run a cleaning with ccleaner, I don’t know what else I need to do.

Ok it gone weirder, now avast thinks himself (AVASTUI) as a phishing scam

What error messages are you seeing from Avast?
A screenshot would help illustrate your problem.

First thing to do if Avast has gone bonkers as you say, is to try and repair Avast.
Open the User Interface
Menu>Settings>Troubleshooting>[REPAIR APP]

Also you may be suffereing if you have Malwarebytes running its real-time protection alongside Avast. I would suggest you uninstall Malwarebytes or make exceptions for it in Avast.

Back to Threat secured. Just started today and get the same message about every 30 seconds. Bloody annoying. Have a screenshot but don’t know how to send it to anyone. Its always the same site which I’ve been using for a number of years https://www.giveasyoulive.com. How can I stop it keep appearing.
