I can’t figure out why (but I suspect it’s the Microsoft Windows Defender built in antivirus but:
My Windows 11 22H2 laptop lags to the point where it’s basically unusable for 30 seconds when:
I plug in a usb flash drive
Download exe, zip files
Extract zip files using Windows Explorer

I suspect it’s the antivirus scanning but is it normal to bog the computer to where it’s not usable ?

If you open task manager you should see a process spike up in CPU usage, which one is it?

It can also be smart screen checking file signatures with Microsoft causing the delay if you have poor internet connectivity (or none)

No, it's not normal.

I have a ASUS laptop with 11th gen. i5 with 8GB of RAM, but it doesn't do that when I plug in USB / HDD etc. It used to be a Windows 10 machine, I upgraded it to Windows 11.

I imagine that you could easily prove if it's windows defender or not by disabling it temporarily and seeing if it's normal...

I haven’t been able to replicate it but I had turned off a bunch of defender settings.
Let me play with it and I’ll follow up when I have an answer
I did update Firefox. I wonder if it was some sort of bug with that. Let me also install the Microsoft January 2022 patch Tuesday updates too

To the first - I had almost all turned off but found the final two settings to also turn off
To the second - yes I turned that off

^I did all of the settings changes when I made the thread.
Maybe it worked- it was just weird because it didn't immediately take effect. Because the slowdowns were still occurring "Day 0" when I changed the settings

I think---I just thought it was odd that the new settings didn't immediately take effect. Maybe I'll re-enable everything and see?

It happened again - the only process (other than VirtualBox) that was the highest CPU percentage was the Antimalware Service Executable which peaked at 7% (when the slowdown occurred)

Maybe it happens because my CPU isn't really meant to use VirtualBox, and thus the antimalware even though it's only 7% is enough to bog the computer down?

What are the interrupt's doing and what is the disk queue when it happens? You'll have to run a trace.

Not to hijack the topic but...am I the only person who doesn't use anti-malware, virus protectors, or anything that is supposed to protect and guard your computers? Since the 1970s I have never used anything...not even firewalls...I either turn it off, disable it, or actually uninstall it from my OS.

One time I got the pesky FBI notice my computer was locked up after downloading and decompressing a pirated file...think they wanted me to send them $50.....guess that was in the early '90s, but since I religously (automatically) make routine hard drive images for backup using the old Symantec Ghost...even that wasn't a problem really...

I intensely hate anything that slows down my computers...and only once in 40 years was I bitten...

Well presumably your broadband router is supplying an edge firewall, or you'd have long since been ravaged by the world and his wife

That stuff and the constant "security updates" are all pushing us closer and closer to operating system as a service. They want you to rent everything and own nothing. It's horrifying.
