I have run into a really bad problem. Avast marked two files in my Thunderbird Mail folder. I moved them to the chest. After doing that, it seems that all of my mail since september last year disappeared!
So, I wanted to move the files back, but the restore choice was "greyed out". I then edited the entries for the files in index.xml to allow restoring. But then Avast complained that the search path did not exist. So, I renamed the search path, and restored the files.
However, when opening them in a text editor, they only contained binary data (while the mail files are in plain text).
I am at a loss at how to proceed, and I guess that my manual tinkering has only made things worse.
Any and all help would be much appreciated. Thanks.
