There is no normal ansswer to this question, it depends on the situation.
If you're uploading files it could be huge.
However, if you've just booted your PC and its sitting there idle with no programs running and you see gigabytes of data being uploaded, thats a problem. Likely a virus.
So gigabytes of data is most likely a virus? Okay, I'm sitting around some kilobytes received/sent every few seconds with web browsers and such open, so that's good. Thanks for the info.
basically if you're not doing anything and no programs are open and theres a lot of data transmitting, thats a problem.
However youre saying you have web browsers and programs open, there is ALWAYS going to be data flowing in and out.
