'An error occurred with the POP3 mail server. Mail server responded:' Alert in Thunderbird

Today I noticed that since upgrading to Avast 8.x errors started appearing in Thunderbird (17.x) and it wouldn't download any messages from any e-mail server (neither IMAP nor POP3).

Thunderbird kept reporting an alert: "An error occurred with the POP3 mail server. Mail server responded:". That's it. No detailed messages as to what went wrong ...

After doing a bit of research I discovered that it had something to do with the recently upgraded version of Avast 8.

The solution ...

It's not that complicated:

  1. For starters you have to open up Avast, which is probably hidden somewhere within the lower-right corner bunch of icons, double click it's icon and Avast's window appears.
  2. Then click on 'Security' and under 'Virus protection' there's a list of shields (which areas Avast protects).
  3. Double click on 'Mail shield'.
  4. Then click on 'Stop' button and 'Stop permanently'.

And so Thunderbird receives messages normally as it did before upgrading Avast.
