Rundll.exe virus?? Please help.

Hello,

I seem to have some sort of virus on my computer. It's not constant, but from time to time, there will be many, many instances of rundll.exe (sometimes hundreds), each one using between 1 and 4 MB of memory. Today I got the blue screen of death.

I've run Malware-bytes anti-malware AND anti-rootkit. Neither found anything. I also ran Rogue Killer, but I'm not sure if any of the entries it brought up are actually problems, or if they're supposed to be there. I'll paste the log below, if anyone could help me out, I'd really appreciate it.

I'm on an ASUS laptop running Windows 7 SP1, 64 bit.

Here's the Roguekiller log:
