Windows 7 Home Premium SP1 64bit, Asus N56VZ
There were no problems and no Trojans/viruses on the system before I installed the latest drivers offered by Windows Update last week (as far as I know).
Before all this happened I made a manual Restore Point.
Backstory: I got Nvidia and Realtek drivers + Intel driver for something. Damn me for not checking. If there was anything else, I can't tell right now and can't access Windows Update. On top of that I updated Avast antivirus to the latest version and uninstalled a few telemetry updates.
After the update finished I noticed severe slowdowns when working and yesterday, after I installed another few KBs, Windows took around 30 minutes to boot and froze on desktop after (with mouse working). Not thinking much about it, I went to safe mode (works fine for a while, however hangs up after a random amount of time) and restored my backup from the last week.
Problem improved after restore, but did not disappear completely. Normal mode boots, mouse works, but then it freezes again. Uninstalling Nvidia drivers completely with utility solved the issue for safe mode. Could the backup/Win Update corrupt the drivers?
Current situation or TL;DR:
It's impossible to run or uninstall Avast in safe mode or in normal, it refuses to run and freezes the system on uninstall with their uninstall utility.
Normal boot with no Nvidia drivers takes normal times but it still has random freezes, but while the system is frozen, I can open the task manager and see that nothing is happening.
Driver check utility causes a BSOD blaming HIDCLASS.SYS (haven't tried running it with no mouse plugged in yet).
SFC /scannow reports an unrelated problem that I solved (group policy files missing).
Hard drive is fine, no problems found.
Event manager blamed audio drivers for long load. Uninstalled Realtek drivers.
Didn't get to memtest yet (laptop run perfectly before the updates).
So, should I try replacing all drivers on my laptop? Any other thoughts?
I would welcome any help at this point, I need this laptop for work.
Edit: Malwarbytes seemingly didn't find anything of notice. Ad-carrying trojan is pretty bad, but not system freeze bad.

Edit 2: Killing off Realtek and Nvidia drivers and cleaning up some files let me boot normally, but, I think trying to use a USB slot causes a freeze (I got one, but it passed after 10 minutes-- Could be something else).
I still need to find a solution for my AVAST antivirus (it's protecting itself... But it's completely dead, unsure how it happened)
And now that I got a boot log, I'll post it here. I cannot read it well, but I do seem to have some additional problems with drivers. I'm trying to locate which Intel driver the update corrupt. And then I'll go see what's the deal with HIDCLASS.sys is. They should be related.

Edit 3:
Found the potential culprit:
Intel System 8/19/2016 12:00:00 AM 10.1.2.80
From Windows Update. A highly suspect update that breaks things.
Will check the other's out too.
Edit 4: I have not been able to locate that Intel update. Reinstalled Nvidia, Intel and Realtek drivers, froze after boot again.
I have no idea what to do next. Please help. Uninstall HID drivers?
