I can't say where specifically I was on the site, I believe it was http://www.nexusmods.com/starwarsempireatwar/? or http://www.nexusmods.com/planetexplorers/? but it could have also been anywhere in the Unreal Tournament 2004, Fallout New Vegas, or Fallout 4 segments. The site it eventually redirects to calls itself Microsoft Official Support System (error8f3.com) but it goes through a rollercoaster of redirects which include: -engine.spotcenered.info (http://engine.spotscenered.info/Redirect.eng?MediaSegmentId=29408&dcid=1_ctx_baead30d-694e-4375-81a4-1c5d322f7aac&vmId=b5a6fe4b-3999-47fe-ad0a-fa08c5e5d142&abr=false&timeZoneOffset=) -https://iasrv.maha-media.com/6/ -and maybe: Improve Your Brain Health - Lumosity (http://www.adsupplyads.com/_adunits/pageunder/index.html?source=d) Encountered it around 10:55 am (if my history is to be believed). No screenshot because did not think to before forcing to close, sorry.
