Any idea how I can set about limiting programs running in the background accessing the internet while I am using my 3G modem on my laptop ? And afterwards being able to reset back to normal !
I only use the modem to check and send emails from home but by the time I have done so, Firefox, Antivirus, Java, Windows and all sorts of other programs have checked and downloaded upgrades with the result that a few kbs of intended information turns into megabucks worth of traffic.
I regularly bring the laptop into the office and connect via adsl to ensure that I get all my upgrades but I still get caught out every now and then when I get my account.
I use the Vodacom service whereby the data card is linked to my cell #
There is a facility where you can check the useage but I have found it to be unreliable and by that time it is too late in any case.
