Constant "Threat Secured" URL: Blacklist notifications?

I got a Threat secured notice from Avast earlier this morning about “i.prcdn.co,” which I gather was blacklisted. When I close the warning, I get another one within a few seconds, which means, I guess, that something on my computer is constantly trying to connect to the blacklisted item.

The specific URL given in the details is hps://i.prcdn.co/img?regionkey=OqmhqQfSihquk0S0QWQBXg%3d%3d&scale=144&error=3, and the associated process listed is Chrome.

When I check the WebShield logs, I notice a few dozen intercepted attempts to connect to variations of that url with a few different regionkeys.

Any clue about how I can resolve this issue and keep Avast from giving me endless warnings? If something is constantly trying to connect to this thing, how do I stop it? I’ve done a quick Avast scan plus a MW Bytes scan that showed nothing and am doing a full Avast scan now. Have also deleted all Chrome extensions except AdBlock, cleared cache/cookies/etc., to no avail.

(FYI, the website that first triggered the blacklist notice, iirc, was a newspaper story I was viewing through PressReader, which hasn’t given me any issues before that I know of.

By way of an update: complete system scan via Avast showed nothing. I’m at a bit of a loss here. Any ideas?

According to these scan results, there is one file associated with that IP address concerned,
resulting in such an alert. Site scan failed - apk Android malware & img??file flagged…

Hi there - was there any resolution to this problem? I had the same issue with the pop ups when trying to read a newspaper on PressReader. Puzzling.

I have had exactly the same problem with Pressreader in the last 72 hours. Any advice for simple users without expert coding knowledge would be welcome.

Report it to avast lab and they will take a look >> https://forum.avast.com/index.php?topic=14433.msg1289438#msg1289438
