I was surprised to receive an email from BT on August 4th telling me I had used 9.54 GB of my 10 GB allowance for the month of August.
At first I thought this was the Olympics causing more than usual iplayer usage, then I noticed that 5.57 GB of this was upload. At my upload speed of 504 Kb/sec this would take about 24 hours.
My net meter readings for the first 5 days of August are 111 MB up and 535 MB down.
I have Norton 360 running, and do not (to my knowledge) have any P2P software installed.
Is the BT usage monitoring wrong or has a virus sneaked through?
