I installed Bandwidth Monitor Pro yesterday. Today I put my computer in sleep mode before I went to work. When I came home, as is the case recently, it was somehow on (I live alone). Vista has always been quirky like that though. However, the real shocker is that according to the software, I downloaded 2GB of data and uploaded 5.59GB!! I do not run any peer to peer software or anything else that would require uploading/downloading that amount of data in one day. Two theories I have: 1) TOR is doing it somehow. I have it installed and almost never use it, and I have it set to serve as client only, not relay. 2) My computer is somehow being accessed externally by someone. (am I paranoid?) Appreciate inputs. I run a router but do not run firewall software.
