win32.banker: Spybot found it, killed it, it came back, Suddenly Disappeared

Hello,

Last night I ran spybot and discovered a trojan called win32.banker. I don't remember what the letters were that came after that. So Spybot supposedly fixed the problem. I ran it again and it still showed up. I tried a couple more times and it still showed up.

This morning, my laptop was acting very slow and choppy upon startup. Out of nowhere a window opened that said windows command (it was black with grey letters) and then it quickly closed and disappeared. I ran spybot again and clicked on "fix selected problems".

I tried to search online to see how to get rid of it. One website suggested Spyware Doctor-- so I downloaded it and installed it. It found 3 main problem with 15 infections, but it wouldn't get rid of the problems unless I bought it. So I uninstalled it. I rebooted my laptop.

However, when I ran spybot again, it said my pc was clean. I ran SuperAntiSpyware and it couldn't find anything. I ran Malwarebytes and it couldn't find anything. I even ran McAfee and it couldn't find anything.


So does that mean it's magically gone? Everything seems to be running fine...Can it suddenly go into hiding so that spybot wouldn't be able to detect it? Now I'm too paranoid to check my email or bank statements.


Thank you so much for your help!
