Yes, I think they are.....except they don't(as far as I am aware) cloak their change in operating system as an update.

My security system highlights the fact that I have not downloaded an important update every time windows updates come online.....and because it sees it as a security threat this makes me a bit twitched. Well, it did. Now I know that this security update is nothing of the sort I will check it out and then dismiss it.
It is this underhand way of going about getting 'converts' that I am strongly suspicious of.
