Possible false positive by Avast regarding Google Chrome and Mozilla FireFox

Google Chrome and Mozilla FireFox keep getting flagged every 45 mins to an hour and a half as having a connection to some anti-malware domain, Urlhaus.abuse.ch, aborted as being infected with BV:Downloaded-AEH [Drp]. I have gone though and done scans with Avast at least 20 times and have found nothing of the sort on my computer except once, and the result was a FireFox cache file (can’t even find what Chrome is doing to set it off), to which Virus Total shows only 3/61 vendors have flagged as malicious. I’ve used scans of every type, used the Rescue Disk, Boot time scan, all turned up nothing. Even Malwarebytes couldn’t find anything, and using System Restore doesn’t work. Non-stop onslaught of alert popups or notifications in silent mode.
This is the Alert ID: 51f6a779e13a/2024-03-24T05:31:39.941Z

Now it is a bit of a pain, disabling one app at a time to find it.

Clearing my cache worked! Avast hasn’t gone off in a few hours! Thanks!

I wonder what the connection to urlhaus.abuse.ch was for?

Something in the cache however it got there was trying to connect to it.

When you visit a site, information remains in cache, why that would want to connect to the site is a mystery, given it is almost impossible to determine after the fact.

What is stranger is:

URLhaus is a project operated by abuse.ch with the purpose of sharing malicious URLs that are being used for malware distribution.
