Please uninstall this shit right now :- ) I am fully serious.

It has no benefit compared to what is in Windows 10, and it's just actively spying on you and selling your data. It's the biggest crap-ware on market.
For those who absolutely need for some obscure reason something 3rd party, NOD by ESET is the only reputable solution.

But actually Windows 10 is more than enough.

- Avast sold user data
- Allowed breaching of VPN
- Is currently banned by all major goverments and businesses
- It was always shit to begin with (just like Kaspersky "I am not russian spyware" Suite)

Well, damn. Better get on it! Had no idea they messed up that bad. Thanks for the heads up man.

hey Juraj bit of a newb question but how do you actually do 1 and 2 that you mention below?

--- Quote from: Juraj Talcik on 2020-02-26, 10:55:26 ---Could you elaborate on your Group Policy settings?

Here is what I do currently:

1) Exploit protection exceptions for 3dsMax & Corona (almost everything OFF, not just Flow Guard)
2) Real-time protection exclusion for 3dsMax & Corona folders (in Program Files, as well as Users&AppData)

I considered this to be a good solution to exclude 3dsMax, but not disable (otherwise excellent) protections. Would love to see some benchmark what further improvements could be done by more drastic measures.

BTW: What's your memory kit ? And what speed is it running stable at 256GB ?

To set exceptions for Max and Corona executables (most likely just needed for Max):

1) Open Windows Security
2) select App & Browser control
3) switch to "Program Settings"
4) Click on the "Add program to customize" button, select "Add by program name" and type in "3dsmax.exe" then click "Add"
5) find and select "3dsmax.exe" in the list
6) click "Edit"
7) mark every "Override system setttings" box in the list and make sure everything is set to "Off".
8) click apply
9) Done.

You can try the same thing for Corona executables but I doubt that will actually make a lot of difference as Corona is mainly a Max plugin so should inherit these settings from Max.

To add exceptions in real-time protection:

1) Open Windows security
2) Select "Virus & threat protection"
3) Click on "Manage settings" under "Virus & threat protection settings"
4) Scroll down to "Exclusions"
5) Click on "Add or remove exclusions
6) Click on "Add an exclusion" at the top.
7) Select "Folder"
8) Browse to your 3ds max folder, enter it, and click "Select folder". Confirm the UAC prompt.
9) Repeat number 8 for the Autodesk and Corona folders in Program Files and "c:\users\[username]\appdata\Local" and "C:\users\[username]\appdata\Roaming" folders.
10) Done.


WARNING!: This is inherently (albeit slightly) reducing your overall security and malicious software, if placed in and run from any of those folders, could still execute successfully and without your knowledge, bypassing security! Make these modifications at your own risk!

Thanks so much for the detailed info - all was done however i couldnt find CORONA in the folder c:\users\[username]\appdata\Local" and "C:\users\[username]\appdata\Roaming"

Apart from that, all else was done and so far, to be honest, no noticeable differences at all.

My material editor is my main issue, always sluggish - on both of my workstations.  Its weird because somethings its snappy - most of the time it isnt.

The material editor being sluggish is the bane of Max. Using only one single thread for the entire interface also doesn't help it much.
I often face the same issue (with the slate material editor) and have found that more often than not, switching it to "Compatibility display mode" helps:
1) Open the slate material editor
2) Select "Options" in the menu and go to "Preferences"
3) Make sure the checkbox for "Use compatibility mode" at the bottom is set.
Unfortunately, this setting doesn't persist between Max sessions so you'll have to enable it every time (I do it if the material editor becomes sluggish).I haven't noticed any visible change in the way things are displayed with it on so I don't really know what it does, only that it can help and does help, sometimes.
For general Max responsiveness, you may also want to try some environment variables as we have described here (this also has some more tips that may be useful):https://coronarenderer.freshdesk.com/support/solutions/articles/12000011479-my-3ds-max-is-very-slow-it-is-hard-to-navigate-in-the-viewport-or-use-the-material-editor-
The environment variables can sometimes help (helped me) but not always. Won't hurt to try them, though :)
