brb.yahoo and frequent stops for ad redirector threats

[readyexec]

Looks like most here are well over my skill set so please bear with me. In the last 3 months I have been seeing pages ID'd as brb.yahoo when I try to click thru stories on yahoo.com Running Win 7 Pro 64. I am also getting tons of popups regarding ad redirectors that have been stopped. Why isn't Malwarebytes 3.3 not picking these up in scans? brb.yahoo does not seem a problem on Firefox just IE11. I have a dup second machine and I do not have these problems on Edge or Firefox or Chrome on that one which is running Win 10 64

Hello @readyexec,

Could you please provide us with some logs so we can look into the problem?

 

Thank you,
