After this upgrade Safari has become a sitting duck for nuisance sites especially MacKeeper.

After the recent update, Safari has become extremely vulnerable to attacks from browser hijacker sites, most notable of all being MacKeeper. Pages either don't load or some other stuff pops up and most importantly "select" and "go back" options are disabled. Tried almost all tricks available free on internet & Youtube to get rid of browser hijackers, but didn't work. As a last resort, downloaded Adguard software, still unable to prevent browser from being hijacked. BTW my system is a Mac 27.5k (2015) running on latest release "High Sierra" version 10.13.1.

Request Apple to seriously look into the matter and design/suggest a fix for this problem.

Thanks & best regards,
