I went on holidays and when I came back I found de WinHound virus on my computer. So I started looking on my historial to see I someone has been surfing the web on my computer. So I found a lot of sites on some days that aparently there was nobody home (porn sites). Aditionaly, as I have a ADSL downloading capacity limited connection I checked the ISP connection register web site to double check it and I found connections with my ADSL user in the same days. So I keeped my investigation and I found out that someone have reinstall de AVG trial antivirus that was expired when I leave (I guess to try to clean the virus/evidence).
So the question is: Is there a way that this trojan can steal my ADSL user and password and start a connection from anywhere else, and that this connection could get register on my internet explorer historial, while my computer was shutdown? Yes I know .... It seams rediculus, but I would like to have a second opinion beacuse if it isn't posible my neighbour is coming inside my home and using my stuff and surely I would have a real big argument when I tell him this. So I thin I have just posted the most funny question ever in a forum.
Waiting for help.
Thanks verymuch
