Hi,
I´m getting a pop-up winodow every minute!
The only thing I’m running is DC++.
It says: "Internet connection timeout elapsed. Continue waiting? (DCPlusPlus.exe → 83.31.149.175:110)
What should i do??
loranga,
I am at a loss to see what your problem has to do with Avast?
Do you have Avast installed?
If so, what is your OS?
What is DC++? An email client?
What about increasing the timeout into email account settings…?
Could be the MS developer studio, but it could also be THIS
DC++ is an open source client for the Direct Connect protocol. Direct Connect allows you to share files over the internet without restrictions or limits. The client is completely free of advertisements and has a nice, easy to use interface. Firewall and router support is integrated and it’s easy and convenient to use functionality like multi-hub connections, auto connections and resuming of downloads.
We need a bit more information before we can venture off into “solution” land. 
Hi Ioranga,
DC++ (similary to some other file sharing programs) tries to overcome the firewall rules and uses TCP/IP ports reserved for other services. In this case it is the port 110, commonly used for POP3 protocol. This trick might work for firewalls, but it also confuses avast! Avast! is trying to check outgoing connections to certain ports (110, 143, 25) for viruses and expect the mail communication on these connections. DC++ does not send or receive mails nor does the remote host respond via POP3 protocol.
The solution is simple. You must exclude the DC++ process from the automatic virus scan.
Find your avast4.ini ( c:\program files\alwil software\avast4\data\avast4.ini ) and in the section [MailScanner] add (or edit) the following key:
[MailScanner]
IgnoreProcess=DCPlusPlus.exe
Multiple process names can be separated with commas.

I also suffer from this, I stepped away from my computer for an hour or so, and came back to find 20-30 of these things in my taskbar 
I applied the workaround you suggested with the 3 P2P apps on my computer, so far so good, but my question is why? Why does this (rather un-informative) error message appear now, and not in a previous release, and I’m guessing a software update is to blame here. I’d rather not tell my antivirus software to ignore applications on my computer, so is there a fix coming that will allow me to remove the ignore?
The ‘fix’ as you call it, should come form the makers of those p2p applications. They let their applications use ports that are asigned to other tasks.
Well that’s funny, since when do mail clients use the ports 6881, 6882, 6883 and 6884? The fix has worked, and I’ve got all my P2P clients using the above ports only. There seems to be a bug in the latest avast! that doesn’t like P2P clients.
EDIT: There is also the fact that avast totally ignores what you do with the error box. if you don’t answer it, another one will pop up X minutes later, if you click yes, another one will pop up X minutes later, if you click no, guess what? another one will pop up.
Sorry Lukas… You will open a hole in your system.
I feel the same… There must be a solution.
Please, take a look on this and see if it’s not possible to get a window with the question: Do not show this warning again… 8)
I’m sure there’s no checkbox.
Me too 8)
I’m asking them to add one ;D
Well I don’t even want to see the error. It wasn’t there in previous versions, and it shouldn’t be there now.
Ok, maybe I haven’t stressed this enough - only mail communication of ‘ignored’ process is not scanned. This brings no other exceptions - file access is of course scanned. In ver. 4.1 this feature was not available, you might also say that all processes were ignored. 
We added the transparent mail scanner in ver. 4.5, since then avast! scans not only mail clients you have configured for this but also all communication to certain ports.
If you believe DC++ sends emails and you think they must be scanned - it’s ok to let them being scanned by avast! But I assure you there are no mails going in DC++ and thus ignored or not, no mail scanning on it’s connection will ever have any other effect that timeout message!!!
The timeout message is there for the situations when sending or receiving of large mail may look like timeout and you would like to wait a bit longer in stead of just silently terminate such a connection.
Lukas.
In other words, the Timeout message here doesn’t really mean a timeout in POP/SMTP/IMAP scanning but simply the fact that the avast mail scanner does not UNDERSTAND the traffic that it’s seeing (because it’s neither POP3 nor SMTP nor IMAP protocol - it’s some sort of proprietary, binary protocol that DC uses).
E.g. when monitoring port 110, it ASSUMES that the communication will follow the POP3 protocol. However, this is clearly NOT the case here – DC is using this port to hide from firewalls (pretending that it’s a mail program when in fact it’s a P2P program).
Does that make sense?
Thanks, Lukas.
Sorry, I think was I who stressed your words.
Vlk, for me it’s clear. Thanks too.
Reading your answers I assure that DC++ was pretending to be an email program (even being a P2P). So the email traffic won’t be scanned (because it’s not a POP3 one) but all other traffic at the same port will be monitored… Did I understand correctly?
Why DC++ has this behavior? Why the user will want to hide its traffic from the firewall?
I’ve been seeing an a lot of these same type of timeout messages from my Thunderbird email program. I’ve gotten these messages ever since avast went to the new style of configuration (i.e. you no longer need custom email server configs.) I have a pretty simple setup:
Win XP Pro (SP2)
Zone Alarm Pro
Avast 4.5 Pro
Mozilla Thunderbird email program
Yahoo email service
DSL
I’ve read all the suggestions about increasing the timeouts on Avast, and none of the suggestions have worked. Thunderbird does not even have a connection timeout setting (unless its buried in some init file.)
So is Avast having some type of issue with the yahoo mail server? I’m on DSL, so timeouts really don’t seem like it should be an issue. Is it a communication sequencing error between Avast and the email server?
Is there some way for me to assist in diagnosing this annoyance?
Thanks
Just as an additional note, the connection timeout error only seems to happen when Thunderbird starts an email check via its “email check time” (I have it set to 10 mins.) If I run the email check via the “Get Msgs” button, I never get the timeout. You can also tell that you are going to get a timeout message in that the avast email scanning icon (lower right toolbar in windows) just seems to hang. After the timeout window appears and you decline to continue waiting from the pop up, the icon goes away.
Hope this helps.
Thanks
Does the timeout message come from Thunderbird or from avast ?
