Avast updates keep freezing my PC
Twice now when Avast needed to update drivers or program, it would start to freeze the entire PC, causing Windows Explorer to hang, the desktop itself to refresh, and basically prevent anything from working while causing 100% Disk Usage.

Is this a bug or problem in the installation and do I have to repair Avast? Cause a restart usually fixes the problem but I don't see why my Avast can't update properly like before without causing the hangups. I should mention I'm on Windows 10 2004. And that the problem only started after I bought their subscription for full protection. The Free Version rarely gave me issues.

Now that you've clearly nailed down the cause, a clean reinstall of it won't hurt. And should the problem persists afterwards, you'll have to take it up with their tech support.
Junk, stop installing Anti-Virus suites.
Use Defender and buy MalwareBytes Premium instead.
I have to agree with the others. I'm not sure why you would have that garbage installed. I consider it worse than bloatware.
On another note I feel like it's not Avast causing the freeze. I've never had a software freeze my pc. Usually a cpu will do this if it's unstable (I'm looking at you AMD FX). A healthy pc will never freeze.

I mean, freezes can happen, especially due to software. They're just rarely if ever THIS bad. I've had games freeze my PC, requiring either a hard restart or if I'm able to access the desktop or task manager, I either restart the PC or kill the offending program. And while yes, Avast is pretty garbage as far as antivirus is concerned, the free version never gave me these problems (probably cause it didn't have to update all the shields that are limited to the Premium version).

My PC can and does become slow for example when Windows Updates or Steam is downloading something (my OS is on an HDD, not SSD), but certainly never unresponsive or breaking the desktop and windows explorer. It also only STRICTLY happens with Avast. On the rare occasion a game causes a freeze up, once again, a hard reset fixes it.

I used a pc that froze before and it was overheating. It would freeze randomly here and there. And then not freeze for a while. And then freeze during a game. Then be fine for weeks. Then freeze at desktop or maybe during boot. Whenever it felt like being a pest, really.
It was my old FX 9590 that had an issue with cooling system all along. The temperature spike would happen so fast that it wouldn't display in metrics overlay. So I had no idea. As soon as I swapped out the cooling system it stopped freezing and I was able to use it for six years straight and never got a freeze again.
Another type of freeze I dealt with before is a hdd at 100% load. This should stop happening though once the drive has relaxed and usage is normal.
I got one more:
A screen only freeze. You can still hear your game running and hear the inputs being made, but screen is frozen on last image! That one turned out to be a faulty cpu. It kept changing how many pcie lanes too. I install it and notice only 8 lanes. So I reinstall cpu and now we are at 16 lanes. I'm thinking.. "ok there's something wrong with this computer" I play a game (I think it was Bloody Spell) and five minutes in my screen just stops and I can hear the game still. I can still swing my weapon, hear the jump mechanic and footsteps ect. So I hard restart the pc and back at 8 lanes. I ditch that damn cpu and replace with the exact same one (i7 3770) and problem is completely gone and the pc still working even today.

So, if you are getting a freeze of any type, it could be inside your pc somewhere and nothing to do with software (besides triggering it).
Cheers

And it does. It immediately relaxes as soon as anything that was causing it 100% load stops doing whatever it is that was doing it. It should be noted that it's specifically HDD DISK USAGE that's 100%, NOT CPU. The CPU is actually fine all things concerned. Only games have ever made it go up (and if they use CPU in anyway, that's a given). The only other thing that ever increased it was bad Windows Updates that broke or caused a bug in a Windows service.

100% disk usage is usually only strictly Avast. Even Windows Updates or Steam downloading something might make disk usage 99%, but that 1% at least allows you to still use the desktop, open a browser (if albeit slowly) and actually open and load Windows Explorer files, because that's NORMAL functioning when it isn't being overloaded by a buggy update or process. Also, I don't get random freezes in games just because.

Most of the time, it's a well-known crash or freeze that occurs due to the game's own engine or poor optimization, and in the past, the only reason I had to hard reset was because the frozen screen would stay over the task manager, preventing me from even killing the program. As soon as I made it so task manager overrides anything else on screen, I could kill the game, and continue using my PC without a restart. Trust me, my CPU is the LAST thing. I know people like to blame a weak or old failing CPU, but I'd sooner suspect my hard drive of failing than my CPU. Especially since disk usage is related to HARD DRIVE.
If realtime scanning is enabled, try pausing/disabling it before you try to update

I actually did that afterwards. I turned off the "Real Time" shield. I read online on Reddit that that's one of the things that causes that problem.

Well, seeing as you have a subscription, maybe you can try to uninstall it using their specialized uninstaller you can get off their website. It supposedly cleans more thoroughly. Then you can try installing it again from scratch.

Avast has a forum also, maybe there are others reporting the same things. Did you check if your hard drive needs a defrag or something? Did you check its health? Crystal Disk Info can check that quickly if you haven't done that before.

Do you have an SSD or HDD as far as the drive that your OS + Apps are on?

HDD. But like I said, the worst that happens is it gets slow during game downloads and windows updates. Never so slow though that the desktop and windows explorer become unusable and I'm forced to restart just to use the computer. Some module or bug in the antivirus specifically overloads the HDD disk usage to 100%, basically freezing up even the command console and task manager (upon my last restart, before it could properly shut down, an error popped up for "cmd.exe" indicating it either couldn't start up or shut down (no doubt the command console attempting to kill programs in order to shut down PC).
this is exactly why I don't touch huge bloated multi-functional software. I just see this as them selling an interface with a bunch of code slapped underneath to make people think they're getting their money's worth. Some premium feature that just got enabled is probably crashing the program and taking your computer with it. That's my guess. Won't figure it out since I don't have an Avast subscription and can't even see what you're looking at. I'd try disabling some features. Maybe you can post some screenshots.
OS and Apps are on a HDD, there is your problem.

It causes a problem due modern OS & AV design.
For years the switch to more IOPS was unavoidable, so anything that scans your data, while in use, on a slow mechanical HDD, will cause major issues.

Use an SSD as Bad Motha recommended, or deactivate file monitoring all together.

Sidenote: i personally would stay away from Avast - too many crappy updates, lack of configuration options, generally not a decent third party security.
A modern PC isn't even usable without an SSD, bottom line. GET ONE.
It even makes old PCs (as long as they have SATA 3.0Gbps or better) like a new machine again.

HDD can only do a very few tasks at a time, if the task is demanding, all the other tasks have to wait, like when doing a Windows Updates or similar. This doesn't happen with an SSD. With my OS on an SSD I can have my PC easily do 20+ things at once no problem. Windows Updates + MalwareBytes + multiple game clients all downloading + using youtube via web browser; and more all at the same time and a decent enough SSD won't break a sweat and your PC shouldn't have hiccups with a decent enough CPU and RAM. But even on a 2nd or 3rd Gen i5 even, having an SSD will make the difference between a PC you can use, vs a PC that runs like it's 1995 still and you are ready to throw out the window.
