Sorry about the lack of information. I am helping out a client of mine. She has a laptop with a 3G connection.
I have turned off Windows Update and Avast, but the computer will use up +- 500MB of data in an hour when she is doing nothing.
In order to see which program is using all her data, I checked the “Ignore local traffic within the lan”. On doing some research I see that certain IP addresses are ignored when you choose this option. I am not sure if these addresses are the same in South Africa, or if this could be the problem. Should I delete these addresses?
Thanks for your help.
