Have you tried connecting your computer via the mobile data connection and just leaving it? Don't actively browse, or do anything. Just sit there and see how much data you use up over 10 minutes?
We don't have mobile broadband anymore - it's been stopped since we moved yesterday. The first instance (that I noticed) started going up significantly when on this site earlier in the week, and it kept going up. I turned it off that night and in the morning went in to check my mail (yahoo) and it started up quickly again - about 10-15mb within a couple of minutes. I wasn't doing anything other than reading one email. I shut down my browser and it kept going up until I disconnected the broadband.
Later that day I went to the library and that's when it went up 70MB in 10 minutes, though it stabilised and went pretty much as normal for the next 1.5-2 hours.
Since being on wireless I have no idea how much it's using. I did a full Norton scan (which found a bit and fixed, not sure what though) and Malwarebytes that didn't find anything.
At no point did I notice the performance being affected, it was only when I could see the usage.
Oh and no worries - I really appreciate your help with this - thanks a lot.
