I have a Windows 10 PC which I have just updated to the latest Windows 10 Insider Preview Build 1709 (OS Build 17074-1002). I now find my PC is haunted with hijacked web pages, unwanted ads, videos, music, etc. I never know where I am going to be misdirected and some sites I cannot access at all without being diverted. Ironically one site I cannot access is Experts Exchange without my PC going off in some adventure of its own.
I have done antivirus scans using Windows Defender and AVG Internet Security Suite. Defender did find some viruses which it dealt with but my problems remain the same. Can anyone suggest a way forward?
I did try to uninstall the latest Windows 10 update but could not do that either, screenshot attached.
