Title: Boot Time Scan not working on Avast Free
Post by: johngcampbell on August 25, 2022, 10:37:04 AM
Hi,

As the title says for the last couple of months the boot time scan is not working on my laptops, a Fujitsu and a Lenovo.

Operating Windows 10, one PC has a few apps the other a basic machine with only Avast and CCleaner as apps.

Anyone else found this issue, running Firefox as the browser.

Cheers

John

I haven't experienced it, mainly because I don't routinely run boot time scans.  However others have and there are a few topic relating to problems.

This appears to be related to the new function to allow the Boot Time scan to be run in the Windows Runtime Environment introduced in Avast version 22.7.  See - https://forum.avast.com/index.php?topic=320488.0 - there are others in that topic reporting Boot Time Scan problems https://forum.avast.com/index.php?topic=320488.msg1691468#msg1691468.

There are also comments about this (related problem) and links to other topics.  This is one of them https://forum.avast.com/index.php?topic=320643.0 there are others but this one also shows how to disable this new function.

There has just been a new program update 22.8 but that has yet to be announced in the forums, so no information on any features or fixes, etc.
This begs the question what Avast version do you currently have installed  ?

Hi,
 
Thanks for the information, much appreciated.

I am using the Free Avast version 22.8.7500.734

Would be easier if Avast came up with a solution, not everyone is a techy person  :)

Cheers

You're welcome.

I think moving to using the Windows Recovery Environment for the Boot-Time scan is a definite step forward, than the pre-historic method before (even if I'm unlikely to use it, other than for testing).  However with many different OS versions, I asked the question about compatible OSes in that topic, but so far no response.

Boot Time Scan now runs inside the Windows RE

Are there any OS limitations/restrictions (win8.1, win10 and win11 etc.) on this new method for the Boot Time scan ?

In another topic Avast has received a support file and is investigating, also support page to be updated:
Hi,

Thank you.

We have received the support file, and our devs are looking into it.
We will also update the support page for Boot-Time Scan to reference the new GUI (WinRE).
Sorry for the inconvenience.

So for the moment it is disable using the Windows RE boot-time scan in the geek:area, awaiting a fix and using the old method, or stop using the boot-time scan for now.
