do you have a wireless network? Last December my wireless network was hacked into. I didn't have any wireless security or PC passwords. I had shared the C: drive up so I could push wow interface updates. They stole my Yahoo mail account from me and changed the password, they opened a EBay account in my name and started sell stuff ( fraud, they didn't have anything to sell ) and it took days to get yahoo to give my email account back. I found out they were on my network by looking at my wireless router and seeing the assigned IPs. I do not believe any software on my side is to blame it was my wide open wireless and my wide open passwords with a workgroup of "workgroup". I have since turned off my wireless (didn't really need it for anything), made a real workgroup name, set passwords on all of the pc, only shared up the WTF and AddOn directories. I did not loose any WoW stuff but I could have.
