By the way, I am not alone with this issue. Just seen this recent thread:

I tried to reproduce your issue on Windows 8.1 and 10 x64 but was unable to reproduce the issue.

Firstly, as I have explained, the issue is not occurring on my Windows 8.1 Pro 64-bit PCs, only Windows 10 Pro 64-bit PCs.

Secondly, not reproducing this on 10 x64 is probably due to you not installing the same set of components as I do, so you are not replicating my Avast installation/setup.

A little note :

SFC appends things to CBS.log but is not creating it.
Those entries can only be there if not everything from avast has been removed.
Unless there is somewhere a flaw in Windows that thinks not everything is removed.

I would gladly completely remove Avast from the affected PCs. Sadly, I am not the developer of this software and as such, I am not in a position to know whether everything Avast related has been removed.

Currently, I have been advised to re-install Avast (see reply #13), which I have done (see reply #14).

I too have the same problem.  I am using Avast Pro v 11.2.2262 on 2 desktop machines and 1 laptop.   The 2 desktops were upgraded from Win 7 Pro ultimate 64 to Win 10 Pro 64 about 3 weeks back and the laptop form Win 8.1 Home 64 to Win 10 Home 64.  Having run sfc /scannow 2 or 3 times on all these machines, I always get the same result indicating corrupted files which cannot be repaired.  The files in question are always AVAST.VC140.CRT files as per the original post.

Over the years I have learned that error messages are frequently long on "error" and short on "message".   At the end of the sfc scan it mentions "corrupted" files.   But in the cs log the incriminated files are not labeled as "corrupted".   Rather it says "Unable to load manifest" & "Cannot verify" for these Avast files.  Are these files really corrupted ?

Windows 10 has apparently added more stringent checking and controls for apps which have not received the latest version of Microsoft's "certification" for use with Win 10.

Could it be that this is the issue?

Could an Avast moderator make a comment as to whether or not this could be what is at issue here?

In advance thanks,
Richard

What Windows 10 build do you have? Would you be kind enough to pack and upload incriminating files to our FTP server (ftp://ftp.avast.com/incoming/)?

Edit: Link corrected, thanks.

drake 127

In reply to your request for information the machine I'm on is running Windows 10 Pro v 1511 build 10586.318.

Using File Zilla I have uploaded to you ftp server a zip file (Avast.vc.140.crt.zip).  I cannot be sure that this is what you want.  When I did a search on my system drive for "AVAST.VC140.CRT" I got a whole slew of hits some of which are in the windows.old folder which still has the Win 7 setup in case I would want to revert to Win 7.   These hits include folders & files.  I was unable to copy everything in these hits to another folder, and that which I could copy weighs around 45 MB !

Given the extremely complicated naming conventions that Avast used for these files & folders it is well night impossible for me to see clearly what's what.   I used the file names that, as best as I could understand given what i saw when searching the cs log file for "AVAST.VC140.CRT., are concerned to select 4 files to transfer to you in the zip package.  Can't be sure given the plethora of files and folders and the complicated naming that this is what you want and need.

Best regards,
Richard

I looked at files you sent me and it was exactly what I needed. It looks like you actually have broken catalogs, not manifest themselves. They aren't necessary for everyday use but they seem to be needed when upgrading OS (or consistency checks). I'll investigate further. I'll try to add fix to next beta (likely Thursday).

Ok drake 127.

Glad I got you what you needed.  I'll be watching things.

I can't really know, but I'm thinking the upgrade process to Win 10 is where some tricky complicated manipulations occurred.

Best regards,
Richard

I am really not happy. Care to explain why you did not ask me for this information, rather than just ignoring me?

Not that I wish others to experience the same problem here, but thank goodness others have shared the same sfc issues, otherwise I would be @#*$ed!!

FYI, all my PCs with this issue are running Windows 10 Pro 64-bit, Version 1511, OS Build 10586.318.

It was certainly not my intent to ignore you. I just hadn't time to address this topic until yesterday. I will be glad to hear from you if the fix works for you in next Beta.

Does beta version 2016.12.1.2268, contain the fix?
