Malwarebytes interrupted with a pop-up alert saying Firefox was trying to connect to IP address

167.71.99.170 (https://urlhaus.abuse.ch/url/348428/),

which apparently might be bad?

Interestingly, the above urlhaus link initially reported the hit on the IP address per a Pascal Geenens (@geenensp on twitter) who writes for a security blog at

Thanks to any and all who might be able to help!

First, let's check your system.

You may have ad/mal-ware. Further information can be found in this article;
https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Hi FredMcD Ran both Malwarebytes and Microsoft Security with no results (full scan of all files including rootkit search). No add ons or extensions install.

Is there some way to dig into what firefox was doing at the time the request was made to the IP?

Those 6 PUPOptio...|Conduit lines aren't part of Firefox. Could be related to an Add-on for Firefox, as Conduit has been known for many years as a "bad player" with their Firefox Add-ons. But AFAIK they have been banned from the Mozilla / Firefox Add-ons website, so they may have been installed from some other website; but even that would surprise me, as far as even being "digitally signed" to be allowed to install in Firefox.

Beyond that, it would be nice to see the full "Location" of the Registry Keys and Values. Like maybe a screenshot of the Save Results ... contents or the text of same. Hard to provide advice with the posted screenshot information.
