Windows 7: Windows freezes 30 min after startup, works in Safe Mode

Windows freezes 30 min after startup, works in Safe Mode

Hello everyone,

I don't know if it's the good place to post my problem, because it's not a real BSOD, but it's still a freeze.

So, here is the full story:
A week ago, I got an update to my Avast Free Antivirus. After I installed it, my Windows began to freeze something like 30 minutes after the login screen.

The problem is the following: 30 minutes after startup (I didn't time, but it's almost always after the same time), one by one my programs begin not to respond, and after a few minutes nothing works anymore. I can still move the mouse, but the interface doesn't react. The only way to shut down my computer is to do a hard shutdown.
In Safe Mode, there is no problem, I'm using SM with networking right now.

I tried to disable all the startup programs, but Avast, McAfee, and some other programs still launch themselves.
BTW, Avast works, so I don't think the problem lies in Avast itself
I don't think it's a hardware issue; I have already done memtest86, checkdisk.
I don't know if the problem lies in Avast itself, or if Avast damaged something during its update. But if you're absolutely sure the problem lies in Avast, I can try.

Here are my specs:
HP ProBook 4540s
Intel Core i5 3210M with Intel HD Graphics 4000
GPU : Intel + AMD Radeon HD 7650M
Sound: IDT Audio Hd

I give you also the dm logs.

Thank you for your help.

does the computer freeze when it is left idle? or it freezes even if you are working?

It freezes almost regularly after 20-30 minutes, and it doesn't mather if I'm using it or if I've left it idle. It's like there was a kind if alarm scheduled to freeze my computer after 20-30 minutes of use (of not).
