I think rharv is onto it - it has something to do with your browser, or AV or MALEWAREBYTS (yes, I read has disappeared - I would suspect whatever caused MWB's to go bye bye may also have blocked/blacklisted all URLs or changed Chrome polices , something along those lines like a "bad actor" ad blocker, etc. )

BTW is this Windows 10 (if yes home or pro?) and have you seen same thing with Win 10 Edge (agin if ti si win 10 or IE if on Win 8 or 7) ???

In any case good luck
