Hi rally, I have a very simple life and none of the above you mentioned are any concern to me, I dont even send emails.
I simply connect some times, and look at IIS, and maybe some other stuff of interest and that is basically it, never download any photos or videos.
We only have 8 Gig's a month between two computers and dont even end up using that.
it is random though and dose not happen every day so maybe it is it with updates that i don't know about.
Thanks for your response though.
Leon
