Thank you folks, for the insights contained in the previous posts.
I should probably have said, it's a W7 machine - I haven't had a problem quite like this before.
I have downloaded a few bits of software recently (eg: up-to-date NET, Pale Moon browser), but as far as I can
tell, none of the install dates correspond to the date on the Switch software. Of course, I can't check now, because
I deleted it - I must remember that in future.
Very irritating - the s/ware may be good at what it does, but I have never heard of Switch/NCH and as it happens,
have no use for a program like this. It's a gross invasion of my privacy, whatever the mechanism used to install it on
my machine. More importantly, it's a corruption of the machine which renders it less safe/secure for me to use.
Just have to put it down as one of lifes' little mysteries, and remain vigilant
Incidentally, it's also counter-productive - I will now never use NCH s/ware for anything.
Thank you for those insights, they will help me keep an eye on this sort of stuff in the future,
