Thanks Perry but I can not find a "boot scanner" on Malwarebytes, hence AVAST Premium.
I was reading through a lot of comments about WIN 10 on Whirlpool last night, and even the more recent ones are being very careful in recommending Win 10 if you are happy with Win 7 or 8.1!
There seems to be very little in the way of improvements and according to several users Win10 is no faster or safer but is collecting a lot of telemetry from users. WHY?
Cunningly, MS have decided to give WIN 10 a large update in mid August, just after the "30 day reverse to Win 7/8.1" policy expires. Another WHY?
I smell a dud and feel like Win10 is a Beta-Tester for maybe Win11 or 12!
How do you feel now after having used Win10 for sometime?
