Computer restarts out of the blue

If i can remember correctly i had 2 browsers open with about 6 tabs each open and another browser had about 15. I also had itunes open but it wasn't being used. I think i clicked the "open all" 15 bookmarks and they were loading and that's when it shut down.

Tonight it did something a little different i had about the same programs opened as what was mentioned above but itunes was playing this time.

I was typing and all of the sudden it went to the log in screen all the while itunes is still playing i had to log back in but it that was about it everything was the same when i logged back in. No errors were in the system log this time.

Just to make sure that your system is clean follow these 8-steps and post your logs on Virus and Malware Removal Forum. A system should not log off automatically while being in use (it is perfectly alright if it does so while idling/in power saving mode etc).

I keep getting an error when i try to update Malwarebytes Anti-Malware.

Its scanning right now(without update) and it says i have 6 infected so far. Does this program remove them as well?

Here is the file.

Here is the Gmer file.

Here are the other two DDS files.
