Alright Em1982, do you have an unsecured WiFi network? By that I mean, do you connect to the internet wirelessly or with Ethernet or Phone cables?
If you connect wirelessly it is very possible that someone is surfing on your unsecured network. If you don't then it is a lot more unlikely but not improbable.
Write back with more details about how you connect
I have an iBook G4 running on Mac OSX and lately i've been noticing some fishy things happening with my internet usage. Namely, I've been 'reaching' my monthy usage limit (and sometimes even exceeding it), without doing much (uploads or downloads) at all. This leads me to think that someone could be tapping in to my internet connection remotely...
So my question is:
How do I find out what's going on? and;
What can I do to stop it??
Any suggestions would be greatly appreciated!!
