About 4 or 5 months ago i was attacked by a backdoor trojan via a keygen (i know my own stupid fault) and ever since my computer has never been the same.
The noticable things wrong are that it is impossible for me to see hidden files and change the options to. Also on boot-up i am presented with the following:

Error loading C:\Windows\System32\mhsmivot\dll
The specified module could not be found.

Error loading C:\Windows\Pbaxonocesogihu.dlll
The specified module could not be found.

Error loading C:\Windows\ijohubirn.dll
The specified module could not be found.

Error loading C:\Windows\System32\xxywWqno.dll
The specified module could not be found.

I think i managed to get rid of most of the Virus by installing Norton360 but there is little things and i just wanted to try and clean it up completely.

I am operating on VistaHomePremium Version 6.0 (Build 6001: Service Pack 1)

Any help would be greatly appreciated.

I have tried to run rootrepeal and it would not complete the scan and kept giving me a blank screen with just my wallpaper.
I then got the blue screen saying something about a crash dump.

Rootrepeal will now not run as it cannot be accessed.
