Recently (past 2-3 days), when I visit MMO-Champion and enter text into a text box, I will sometimes get a spam popup in a new tab. The weird thing is, if I have MMO-Champion open in one tab, and I enter text into a textbox on a different website in a different tab, the same spam popup will occur. This only happens when I have MMO-Champion open.
I've done a scans with Malwarebytes and Windows Security Essentials, and I haven't found any spyware or viruses. I've checked through my processes, and nothing new stands out. I don't have any Firefox extensions.
Anyone else experiencing this problem, or know what could be going on?
