Malware causing system to reboot? Possibly Win64\sirefef.P

I started having a problem with one of my computers this morning.
What looked like the Adobe Updater came up already downloading, and now the computer restarts by itself after about 2 minutes.
Security Essentials says it's Win64\sirefef.P, but the computer restarts before I can do anything, or before any programs can get rid of it.

I've ran the recommended programs, but the computer restarts before most of them can finish.

Here are the files from the programs that have finished or nearly finished.

Thanks in advance for any help.

 

Found out how to properly run FRST64, the correct log is attached.
