This is a screen for what I see. Sorry I am a noob at this computer stuff >_>

That clean boot link you sent me tell me a bunch of settings to change. will it be easy to revert them back to normal?

Clean boot, you untick the box. When done you tick them again

On task scheduler, in the left pane click on the various categories. You will see the schedules in each.

Zero hour came. The computer still slowed down. No abnormal processes were being done and no cpu increases were detected. I let it run until 12pm today until I restarted (had to force reboot)

I ran another maleware scan on spyware doctor, and the other maleware program. both were negative.


EDIT:

Investigating the logs....

An hour before Zero Hour:
Activation context generation failed for "C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll".Error in manifest or policy file "C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll" on line 3. The value "MAJOR_VERSION.MINOR_VERSION.BUILD_NUMBER_MAJOR.BUILD_NUMBER_MINOR" of attribute "version" in element "assemblyIdentity" is invalid.


When stuck in shut down:

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the sdCoreService service.

Lets think about this for a minute, together.
Every night at the same time

Has to be something running in the computer or
Something external affecting it.

We did malwarebytes
Antivirus and both an negative
You say that no process began to run at that hour

Im at a loss
Those are the only possiblities.
A malfunction happens anytime.

Put it in clean boot state for the entire period that the problem occurs.

=( I'm really just worried. My computer was made by PowerSpec. Maybe they have some sort of program running at that time? but that would be detected with maleware. gah this is so frustrating.

Before doing clean boot, physically disconnect your PC from net. That way you'll determine is it something external causing the problem or not. And way are you sure that the trojan detected is false positive? Are you absolutely sure about that? Do google search for it, or upload it to VirusTotal - Free Online Virus, Malware and URL Scanner see the results

You may want to uninstall Adobe reader, and try one of this:

Foxit Software - Foxit Reader for Windows

Tracker Software Products :: PDF Creation Software, Free PDF Viewer
They are great, fast and FREE pdf programs, and widely recommended from members of this forum and around interwebz

Just a thought:

If you have automatic Windows updates turned on, this is the time of day it is normally set up to take place and can be delayed by rebooting. I have noticed the same effects when "automatic updates" are being made, particularly on the first hours of the update dissemination to millions of computers. The automatic updates often make everything slow as molasses in the refrigerator. Also, the "automatic" update takes forever.

Next time you notice, do a manual update of Windows...

how do I turn this off?

EDIT: Zero hour came early today. 5 after midnight, and 10 min after a fresh reboot in clean boot mode..... everything came to a crawl.
