Re. suggested d/l of Ccleaner ... DON'T!!!!!!!! ... unless you want an unasked for and invasive installation of Google Chrome and some email/browser device calling itself Incredimail or somesuch rubbish. I foolishly assumed that a download and installation from Cnet would be fine - not so. This takeover of my computer was carried out WITHOUT any warnings or advisory info and has taken over half an hour and a GREAT DEAL of irritation to rectify matters via System restore - and I STILL CAN'T GET RID OF GOOGLE CHROME
To say that I'm unimpressed is a vast understatement.
I'm surprised that GG should have approved this idea - his previous inputs have been unfailingly helpful.
