I feel your pain - Anita
After the update, an very annoying Malware appeared when using Chrome and Safari
(an unwanted adware-type program (PUP) called
Turbomac.
It replaces Googles Adchoices completely

Aswell as pop up Ad banners everywhere on a page,
it will even break up a post and plonk a leaderboard amongst the text :
What a Son .Of. A. B to get rid of
Luckily Firefox is unaffected. Downside is Chrome runs faster and became my default.
But a lesson learned not to clickthrough any of the links or the intrusive Ads on this site.
