"Avast have just not tested all possible scenarios on all platforms"
You're asking for something that's virtually impossible.
I've personally installed Avast on many systems from Windows XP through Windows 10 and
have had very little problems. I do have 1 system on Windows 10 that refuses to allow me to save my Avast settings.

(Sorry, I've taken this off topic)

I too have installed Avast on many PCs over the years and in the main Avast was rock solid. It is only recently (in the last couple of years) that I have seen issues appearing, especially with custom component installations.

Hello,
Every week, I run the command SFC / scannow before i make a backup of my C drive.
so far I've never had a problem but today Avast has just done an update and  the ommand SFC gave some errors on the file "Avast.VC110.CRT".

see below:

Cannot verify component files for Avast.VC110.CRT, version 11.0.60610.1, arch amd64, versionScope neutral, pkt {l:8 b:2036b14a11e83e4a}, type [l:5]"win32", manifest is damaged (TRUE)
Cannot verify component files for Avast.VC110.CRT, version 11.0.60610.1, arch x86, versionScope neutral, pkt {l:8 b:2036b14a11e83e4a}, type [l:5]"win32", manifest is damaged (TRUE)
Repair complete
Committing transaction


I restored my system with my previous backup and disabeled the automatic update in Avast  internet security until you resolve this issue.

Many thanks.

Hi.  Subsequent to my initial post on June 5 and Avast team drake 127's statement that he would try to fix the issue in an upcoming upgrade, I had been waiting for my AVAST Pro v 11.2.2262 to upgrade.  It did so just the day before yesterday to v 12.1.2272.

The problem persists.

Here's how i solved this sfc error; i won't go into details how exactly to do every step...don't ask me how to take ownership, load a registry hive, etc, google it. You should do that only if you plan to completely uninstall Avast and replace it with something else! If you reinstall it, the sfc errors will be (sadly) back...

1. Uninstall Avast with avastclear
2. Remove every file with "avast" in it's filename (everywhere, even in winsxs); take ownership if Windows doesn't allow it.
3. Remove every avast reference from registry
4. Boot your pc with any WinPE service disc/usb that has regedit (i recommend Sergei Strelec WinPE, Hiren's Boot CD is also ok), load the COMPONENTS registry hive (it's in C:\Windows\System32\config, backup it first; you may need to take ownership and/or unmark it as read-only)
5. Remove ALL avast references from the loaded hive, close regedit, restore COMPONENTS file ownership (if you took it) and restart
6. Run sfc /scannow and check if there are still avast-related errors; run dism /online /cleanup-image /restorehealth too just to see if everything else is ok too.

I've used Avast for 10+ years, recommended it to literally everyone and was never disappointed until Win10 came...hours of wasted time with OS reinstalls on my and customer pc's because dism kept failing at 20% (avast locked it, would never suspect that), then those false sfc errors...

Hello everyone
It is probably outdated but the problem is FINALLY solved. I just finished my second win10 64bit pc. In brief I uninstalled avast free with revo uninstaller, deleted all files containing avast from c: (including winsxs manifest temp files etc), cleaned up registry from all avast containing records with regedit and after a reboot I did a Repair Install of Windows 10 with an In-place Upgrade following this guide http://www.tenforums.com/tutorials/16397-repair-install-windows-10-place-upgrade.html. After that I ran sfc/scannow which actually DID the necessary repairs, rebooted and voila. System file checker now reports NO violations. And yes I rechecked after reinstalling the latest avast build. Everything works as it should
Cheers

Glad you fixed the issue on your PCs, but from my point of view, I don't regard an in-place upgrade of Windows 10 as a reasonable solution to the problem, especially when you consider the number of PCs I administer, that exhibit the problem.

As I understand it, Avast are to release an installer that will check for rogue WinSxS files/registry keys and perform any necessary fixes. Hopefully, this will finally resolve the underlying sfc corruption.

I agree, an inplace re-install of Win10 should not be the solution to this issue. It has plagued me for two months now and I am looking forward to a fix that will solve the SFC scan error.

I may have missed it, but is there a way to take ownership of the avast files in WinSxS such that I can manually delete them:

C:\Windows\WinSxS\amd64_avast.vc110.crt_2036b14a11e83e4a_11.0.60610.1_none_d58a6d64ab65b396

The solution suggested at AskVG for changing ownership from TrustedInstaller to my admin account fails as no dialog opens to add a new userID at the Security panel in question.

The Take Ownership script provided on ASKVG has always worked for me on Vista to Win10 http://www.askvg.com/add-take-ownership-option-in-file-folder-context-menu-in-windows-vista/

For a large number of PCs where you would want a quick automated and reproducible solution I think that AVAST developers need to provide us with .... something.
For one or three PCs (like in my case) I found rather handy an inplace reinstall. Above all it solved for me the problem after a month or so of fruitless efforts. In general I totally agree that this should not be the solution but nevertheless it is one effective solution. Before this I simply could not solve it no matter what. It took me at least one hour to uninstall avast, clean the registry and all files (including WinSxS) especially because I had to take ownership for each file/folder, before deleting them. Even after having deleted everything the sfc errors were there. That is why I resorted to the inplace reinstall. That took less than half an hour and now I am a happy puppy again.
Cheers

So you have installed the registry script and have "Take ownership" added to your context menu?

Yes, and when used "permission denied" is the error message.

Sounds like you might need to run some logs so one of the specialists can have a look at what might be wrong with your system.
