i use a dial-up connection to access internet through my windows 8 laptop.the bandwidth usage has been crazy and without any explanation. for example: last day i was just browsing through the internet for 20 mins (no videos) and that ended up costing me about 200 mb from allocated bandwidth.i am pretty sure that something else is gulping through all my bandwidth because after that when i closed google chrome i noticed that the usage chart kept increasing and it soon became 250 mb in about 6 minutes.please help,i want only google chrome to able to access the internet when i connect and no other software or app.
