Computer help please
Something strange has been happening since last night. At home we have mobile broadband with a monthly limit and we can track the download usage regularly. Usually visiting a basic site like checking email or this site would use very little - estimating 10-20 MB per hour. However, it's shot up significantly, where it could use that amount per minute! Even by shutting down my browser it kept going up until I disconnected the broadband.
I'm at the library now with my laptop which also tracks usage and I've been on for less than ten minutes and it's already used nearly 70MB, and I've only come onto this site to post this message.
Anyone know what could be causing this? It seems something maybe is working in the background of my computer? Don't know if I should be concerned going forward, even when we get onto unlimited wireless from tomorrow night.
I'm not tech savvy so any help would be greatly appreciated.
All I've got...all I've got is insane!
