I have been hacked

[delamite]

Started my PC this morning and my WIN7 Pro login password had been changed, with the hint changed also to: ha ha .

I do not do anything online to provoke malicious behavior from ppl, how did they get in?? I am running MS security essentials on this PC as well. The only use this particular PC has is for watching TV channels online. That's it, nothing more.

Furthermore, I only plug my router in when I am home, leaving no connection availible for most the average day.

I am really boggled here, any advice or idea's on how this happened would be appreciated.

Does anyone else have access to your PC, who could have changed the password and hint?

absolutely no one has access to my PC's. Now I just noticed something else odd, my router is unplugged, and yet I am seeing my wireless connection avalible..??? How can that be?

I take it that you access the Internet wirelessly? If so, what kind of protection are you using? You should be using WPA2 (if available), but even WPA (and, dare I say, WEP) is better than nothing. If you are already using protection, consider changing the password at the very least.

pretty sure I am using WPA2,
however, I am going to start with my router and change the password as you say. I am going to do this via ethernet cable directly into my modem as well, by passing wireless completely. On my other PC I am using what I consider a high quality anti-virus program, just finished a deep scan with no reports of anything.

funny thing is: my only affected PC that I can tell was the one with a generic wireless keyboard. Is it possible to key log a peripheal hardware like this?

Have you used a flash drive from someone else, or did you loan your own flash drive out? Did you update any hardware?
