Can no longer add exceptions to File Shield

Program version 26.4.6207a (build 26.4.10932.980)
Windows 11

Today I’ve found that I can no longer add exceptions in File Shield:

  1. Main menu - Explore - File Shield - Open File Shield - Exceptions - Add an exception

  2. Browse to an .exe in Program Files or in a root folder I’ve made myself

  3. Click Add

==> The blue “Add” button plays its momentary shrink animation to show it has been clicked, but the “New exception” window with the Add button stays on the screen as if it had not been clicked.

If I click Cancel to close the window, and check the Exceptions list, the selected .exe has not been added to the list.

I didn’t use to have problems adding Exceptions in File Shield, so this seems to be a new development. I tried removing some obsolete entries from the list in case I had too many exceptions, but am still unable to add new exceptions.

First, I’m an Avast user and not an Avast Team member.

Whilst I’m using Avast Antivirus Free (26.3, yet to get offered 26.4) and not Avast One, I have never experienced this. However, I don’t have a lot of exceptions added.

They are websites that I use regularly and are trusted and ordinarily require you to log on at times Avasts scanning can interfere with this logging in. I only have one exception on my hard drive and that is my exclusions sub folder, for programs or files that I don’t want scanned.

How many exceptions do you have (?) I,m not sure if there might be a limit in Avast One.

I had 43 file exceptions, although as I mentioned I removed some–four or so–and still couldn’t add a new one.

I removed more obsolete ones and got down to 18 exceptions just now, but still can’t add a new one.

Weird I wasn’t aware of any limitation, as I said I don’t have that many websites and small programs that I don’t want Avast interacting with I keep on a different drive in a separate folder.
