It is there, people have changed it in the past (see alanrf’s post).
When I first installed Avast (a couple of months ago) I too experienced timeouts. I increased the timeout in Thunderbird from the default 45 seconds to 120 seconds and have had no timeouts since.
I don’t use Thunderbird, but I would look in the same sort of area, Tools, Accounts, select the account and select properties. I know thunderbird doesn’t have an off-line help file so you will have to dig around to find it.
What version of Thunderbird you use?
I’m using the 1.0.2 (20050317)…
An older one… the last available Brazilian Portuguese 1.0RC1 (20041201)
Maybe the version could be the problem…
For me, the solution ;D

Thunderbird does not provide a way of changing the POP3 timeout in the GUI. You need to create a user preference override.
You can do this by creating (or adding to) a file called user.js in your Thunderbird profile folder.
To change the POP3 timeout add the lines:
// Increase pop3 timeout:
user_pref(“mail.pop3_response_timeout”, 90);
In this example the timeout is set to 90 seconds (instead of the default 45 seconds of Thunderbird). Adjust the time as you need.
Thanks for that, I’m sure it will be a benefit for other Thunderbird/avast! users.
Thanks Alan… Can we tweak more? Is there a list of possibilities?
Yep, the solution to work with avast!, but it works very well with other AV, so I think that the avast developers should make something about this…
Thanks 
m.m
I continue to have this… 
Can the developers correct this, please!?
Thanks
Did you try increasing your timeout in Thunderbird or are you just insisting that the Avast team fix this?
I can reply to you with some questions:
Why do we have to change a lot of thing in the other program to work fine with avast!?
I not just install avast! and everything works fine?
I do this with others AV’s without any problem, only with avast! I have to change the config file, and hidden settings of other programs. Do you think that this is normal? I don’t…
Think about normal users that just want to install an AV and forget it… With avast! this is impossible…
If something isn’t working and you are offered a suggestion that may fix it, yet you chose not to try it because the program doesn’t work out of the box, is your choice.
It can take time to scan incoming or outgoing email, during that period your email program is awaiting a response from the server after its fixed delay time period it pops up the warning.
Not all AVs scan email, not all AVs scan at the same depth/degree, so it is hard to make a balanced comparison.
Not all AVs use a localhost to scan email prior to it getting to your inbox (this does take time) and potentially causing harm, waiting fro the email to be downloaded to the inbox (and saved on your HDD) may be faster (and not cause a time out pop-up) but to my mind this is a lessor level of protection. Life is full of compromises.
Thunderbird has a default of I believe 45 seconds OE has a default of 60 or 120 seconds (mine is set to 90), which is correct? whichever suits your needs. avast! can’t always cater for every email programs settings directly out of the box, so some fine tuning may be required.
NOD32, KAV, BitDefender, AVG, Symantec…
Only have problems with avast since the default settings in this version was changed…
If works fine before, why change? Why not adjust to all the majors programs?
And I’m not speak only about me, but for the others users that doesn’t perceive nothing of computers…
These users just want to install the AV, and don’t want “complicated” settings to change…
I know some users that install the programs, if they doesn’t works, just uninstall and try other…
But this is my opinion…
NOD32, KAV, BitDefender, AVG, Symantec... Only have problems with avast since the default settings in this version was changed...Do these use the localhost to scan emails? Are you talking about the update that included the transparent set-up of ashMaiSv.exe or something else?
If works fine before, why change? Why not adjust to all the majors programs?Which version from - to what change? Adjust what Major programs?
But this is my opinion...As is your right to ignore a suggestion which may resolve the issue.
I’m talking about receive email throught Thunderbird…
The antepenultimate version…
In my case, I have to change Thunderbird and a setting because Ad Muncher, but now avast have more incompabilities…
I don’t said that I will ignore the suggestions, I just want a better solution for the problems…
Alwil team, why don’t you say anything? From time to time, we, the users, get lost without official support… This lack of support makes the things worst.
I believe that changing the default timing in thunderbird will ultimately be quicker than waiting for a better solution, whatever that may be.
