Help needed asap- pop up on forum

[RetroMonde]

I was reading the forum tonight and am seeing a pop up randomly appearing. It's a thumbnail size eBay ad. I saw it on 2 diff posts so I logged out, cleared my cache and restarted my laptop. I thought it was gone but it's still there for me, stuck on the click to post button. I'm on my phone now. Help? Advice? We been hacked or something? Ugh 😑
