Hi LowRider !

Looks like a solution is not forthcoming from Avast. :frowning:
As you said, disabling shields is not an option.

Too bad Avast does not recognize Eudora for what it is: an e-mail client with a fast and powerful searching capability. It also has a mbox data structure which stores attachments as individual files in one folder and does the same with embedded items in another folder. No other e-mail client does that.

Just do a System Restore and things will be back to normal.

After that, do what I do: I just disregard any notice from Avast for any update and keep on working with the version that does not give me any problems.
