Hiya, this is my first time posting here (hope I have all the prerequisites, and I did follow that beginner's guide here). I'm having troubles with Aurora; it seems pretty well-known here. It's actually the second time my computer's been infected with it-- the first time I was able to take care of it looking at solutions posted here for other users.
I've tried the same methods I used last time, using the recommended programs like Ewido, CCleaner, and the nailfix. It doesn't work, though. Specifically, I get stuck when I'm in safe mode trying to run Ewido. The scan freezes; stuck for an hour on 0.0%. I've restarted and tried this several times. Skipping this and trying other thigns doesn't work, but I'm sure it's not just this one program getting stuck that's the problem...
I was hoping that it would help to have more specified answers, instead of just going by everyone else's solutions.
Here's the log!
