Hey. I only found out yesterday (and by accident) that there is more to these forums than just this one. I'll check them out when I have the time.

Onto your instructions.
Trend Micro Housecall
I failed to find the option to generate a report, even though I scanned twice. The first time, it removed a few files; the second time, it only found one: mscornet.exe in /system32 - but it had been there the first time as well, so apparently Housecall couldn't deal with it (it looks like it has subsequently been removed by smitRem, as you can see below).

(This file is an ad plugin for a communicator I rarely use; I don't think it's hostile, but I could, of course, be wrong)
