Intel Bug Meltdown/Spectre Win 10 Update - Contact your Anti-Virus AV to confirm

system · January 4, 2018, 8:59am

Microsoft have released an update for the Intel chip bug - however the update is only available for machines with compatible antivirus.

Is AVAST compatible?

info from MS:
Due to an issue with some versions of Anti-Virus software, this fix is only being made applicable to the machines where the Anti virus ISV has updated the ALLOW REGKEY. Contact your Anti-Virus AV to confirm that their software is compatible and have set the following REGKEY on the machine
Key="HKEY_LOCAL_MACHINE"Subkey=“SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat”
Value Name=“cadca5fe-87d3-4b96-b7fb-a231484277cc”
Type="REG_DWORD”
Data="0x00000000”

Yes we are compatible, a microupdate was issued yesterday

system · January 4, 2018, 9:33am

That’s great - thank you!

I don’t seem to have the reg value though, what version of Avast Endpoint Protection includes the fix?

Spec8472 · January 4, 2018, 9:43am

It should be present on all Avast 8 or later versions, what is your version?

system · January 4, 2018, 10:28am

Avast Endpoint Protection 8.0.1609

system · January 4, 2018, 11:25am

Should I restart my PC or not? Because I still don’t see the aforementioned registry key.

My spec: win 10 pro x64, avast free antivirus 17.9.2322 (vps: 180104-0)

system · January 4, 2018, 11:57am

Still not present after mine has been restarted.

Spec8472 · January 4, 2018, 12:05pm

Microupdates are delivered once per 12 hrs period, and restart is not required for this microupdate. Can you please provide console output from AvastEmUpdate.exe /debug or AvEmUpdate.exe /debug? It must be executed elevated.

The problem is that your updater don’t support microupdates at all, we will solve this ASAP

Edit by Lukor: only early versions of Avast 8 don’t support microupdates (they support emergency-updates though and we’ll deliver the patch by this channel), if you are running any version from recent years you should get the fix automatically

Thank you!

mcorelan, can you please provide content of your “c:\ProgramData\AVAST Software\Avast\AvastEmUpdate.ini” file?

system · January 4, 2018, 2:23pm

[Config]

forget what I wrote]

I had to run the Update from the console and then it worked.

Hi Jack201, yes, you’ve got it.

system · January 4, 2018, 5:49pm

Thanks for the quick reply!

system · January 4, 2018, 7:30pm

The contents of my AvastEmUpdate.ini is

[Config]
LastAppliedPatchId=378

Is that okay?
EDIT: I only realized another forum section lead me here and didn’t pay attention that this is the Business Endpoint section. Sorry. Was not paying attention.

system · January 5, 2018, 12:52am

Hello. Need some assistance. I have not received the patch yet from Microsoft for the Spectre/Meltdown bug. I would love to check to make sure my Avast Free version has received the micro update.

I am running Windows 10 on an Intel i7-6700 CPU @ 4.00 GHz

This is what I have:

Avast free version: 17.9.2322
Avast Virus180104-2

AvastEmUpdate.ini

[Config]
LastAppliedPatchId=371

AvEmUpdate.ini

[Config]
LastAppliedPatchId=378

Not sure how to run this command from console:

AvEmUpdate.exe /debug

Let me know how to run this and I will get you this information.

Thank you in advance for your assistance!
