MY MALWARE EXPERIENCE,  when trying to locate and download "Before the Flood" movie
Used Chrome: found desired movie not available Netflix (only DVD version); googled sources.  Found several offerings of "free" movie are selling a paid service trial of "free" download.
After my search, finally found a movie source, which I downloaded via Torrent.

RESULT: movie downloads and plays.

HOWEVER,  Chrome now loaded a new/random unwanted tab every couple of minutes (after a VERY brief one or more page redirect).  Initially Chrome seemed as unable to leave a *.ru page.  Behaved like malware "Private.mixplugin.com redirect"

UNSUCCESSFUL ATTEMPS TO REMOVE MALWAY FROM CHROME:
Uninstalled and reinstalled Chrome.  Ran a special Chrome cleaner (from Chrome). Ran Defender full scan, malwarebytes.org; adwcleaner; Hitman Pro 9following https://malwaretips.com/blogs/remove-private-mixplugin-com/
Finally uninstalled Chrome for good.

BOTTOM LINE: I wasted a several hours.  I should have immediately downloaded my desired movie from http://www.thepiratebay.se.net/
