EWG

I also have this problem. I'm getting these popups on both IE & Chrome. MalwareBytes blocks them but if I run a scan; no threats. It seems to me that something is running in the background hidden on my computer that is causing these popups and is likely trying to hijack my browsers. From what I read thus far rfihub.com is some kind of Adware, a nuisance for sure but has the potential to unleash some really horrible stuff on you computer like ransomware.
