My computer was infected by a trojan horse. My AVG antivirus caught it, but it still infected my computer. I didn't know what to do, so I deleted some files... which I thought were a part of the trojan horse. Anyways I tried doing system restore, but it wouldn't work. So I shut off my computer and tried booting it in safe mode. But it stopped at the loading driver isapnp.sys. I then tried going to recovery console by booting from a disc, but I don't know what to do. I'm stuck at the sorry for your inconvenience your computer shut down screen. It gives me the options to boot from safe mode, boot normally, or last best working settings. I trried it all but, I got no where. In recovery console I tried fix mbr and fixboot, but none them work.
Please, i'm desperately in need of help. i've been working on this for about 3 hours now. I have no other ideas. Please, help

I'm taking risks, and I don't know what i'm doing. I think I messed up my comptuer and just lost all my files. Did the repair install **** up my computer?? I went to recovery console and deleted all drivers with 0 kb it starts up but it's attempting to reinstall my computer.
Ok i've come close to the problem. Now this is where i'm at. I repair installed my computer. I shut down during the setup because I thought it was reinstalling my computer. Then I tried going back to it, but it's stuck in a loop. It keeps restarting itself... It says Setup is restarting. Should I try fixmbr in recovery console? I tried repair reinstalling it again...
If anyone is following my problem, please... I sincerely request your intelligence in this matter. I've been working on this for about 5 hours now. I haven't even fixed the main root of the problem, which is my hard drive being infected by a trojan horse. But I will get to that when i fix this loop. Thanks again
