But when I go on the internet to install adaware it doesnt detect the usual 18 spyware that came with my computer
instead it detects 8 is there any clue to this?
You seem to call 'track history' of adware. Lavasoft Ad-aware makes the distintion between one and the other.
Probably when you go to Internet and download it, some cookie, recent files used... etc. etc. make the difference.
Never mind if, after all, you scan your system and get it cleaned.
P.S. i know some microsoft updates come with alexa but why?
MS bought the company which makes Alexa and stay with some of Alexa features regardless the spy behavior of it
