Corrupted OS. Can't restore system/repair/backup.

Hi. Let me just state up front that I cannot run DDS. It immediately closes when I run it. I can't run HijackThis either, because apparently MSVBVM60.dll is missing from my computer. But I downloaded the DLL from a website, so I can run it now. This is the HijackThis log generated:

My uninstall list turned up a blank (no software at all; nothing to save). I'm using Windows 7 SP1, 32-bit.

My computer failed to start up the day before yesterday, after I accidentally copied and ran a malware EXE of some sort (it disappeared after I ran it). When I boot up now, it first tries to repair the system, but fails. If I try to do a system restore, it'll fail too. The same goes for backing up. I really hope I won't have to lose all my research data and personal files I'd be so glad if you could help.
