Couldn't open riched20.dll
That's the fscking nimda virus. We had it for six months at school (inept admin, she didn't listen one bit to my telling her that we needed to quit stomping it with FixNimda.exe and RUN WINDOWS UPDATE)
Nimda drops those .eml and .nws files on every open share it can find.
The way the thing infected your machine was when you clicked on it (once). Microsoft, in it's infinite wisdom decided that the left pane of My Computer, et al, would preview HTML, nws, and eml files. The preview function runs the trojaned EXE code and installs nimda. Without opening the file.
I got bit by that too, I tried to open it with notepad and it infected me, and I lost what little credibility I had in the computer department for a couple of months.
