What is this link and why is it blacklisted?

Hello Avast community, So recently I have ventured to cheaper than dirt, sgammo, ammo to go, and amazon. All sites I have used before. May 14th I started receiving random alerts about URL:Blacklist mainly from “assets.pcrl.co” . The alerts are becoming more common since this morning. Recently the alerts have occurred when i open a new chrome tab. I haven’t tried reinstalling chrome if anyone is wondering. This is my school laptop so losing it would very much suck.
Attached are 2 screenshots. One of the most recent alert, the other a list of alerts.
Thanks for your help
