Ok, this is my fucking third time posting about my account's password getting changed and it's narrowed down to me having NO rats, keylogs, ANYTHING. I was running Powerbot, the script "Nova Mine" all of a sudden i see Powerbot closed.. i go to log in because i knew something was up, password changed. i KNEW Powerbot couldn't be trusted, but i've used it since 09. i wonder if maybe its just the script/script writer..
Like singer said, it can't be the script writer.
You might want to search around your appdata and look for random EXEs.
Go through your processes end weird ones and go onto msconfig and turn everything off startup apart from your AntiVirus.
I'm pretty sure you have a rat in your pc.
Powerbot wouldn't close randonmly unless Java crashed or something like that, which is unlikely to happen.
If I were you, I wouldn't use an antivirus, I hate them, they try to delete the viruses but they just make things worse.
I recommend you going manually through folders like Application Data, Windows, System32 looking for weird exes, same with the Registry and Msconfig.
I don't think Powerbot hacked you. The only time something went as bad to as what you've described, is when that greedy ghost kid hacked everyone. Don't worry though Mr.Su has a better staff now!
