Avast 4.7.986 blocks mail client access to POP3 server
« on: April 30, 2007, 02:01:26 PM »
hi everybody,
I recently bought a new desktop system with Vista Home Basic installed.
After I installed AVAST (which I have been using on my WinXP for long time,
without any problems), I got the following problem (Avast version 4.7.986):

when all the AVAST fuctions are switched on, the mailclient which came along
with VISTA, i.e. Window Mail v6.0.6000.16386 (vista_rtm.061101-2205) cannot
get access to the POP3 mailsever of my provider.  The same is true for the mail-client Mozilla Thunderbird (Version 2.0.0.0 - 2007326).
Interestingly enough, I have also installed Outlook 2002, and there is no POP
server access problem with this one.  However, I do not intend to use
Outlook 2002 as my mail-client, since is is pretty much outdated.

Now comes the interesting part:
If in the Avast On Access Scanner, fraction "Internet Mail", in the
"residential tasks", under "POP", I uncheck the box "check incoming mail",
the problem disappears (for Window Mail as well as for Thunderbird).
If I check the box, the problem is back. 

Remarks:
1) The only other security software that is installed is the Windows
Defender which came along with the system. Version is 1.1.1505.0, Modul
1.1.2405.0
2) My internet connection for the VISTA Desktop is done via Ethernet LAN
connection to a WinXP Desktop (Home network).  The XP Desktop connects to
the ISP via cable modem.

The two questions I now have are:
1) What can I get this situation repaired?
2) How safe am I with leaving the box "check for incoming mail" unchecked?
I assume this really means a security problem, right?

Thanks in advance for any help - best regards, Erich

Is ashMaiSv.exe allowed to connect the Internet?
Do you use any spam killer application?

It's not good having it unchecked, of course.
You can do a workaround to it setting the Standard Shield sensibility to High level. But let's try to solve your original problem...

Maybe you can add the following line to the [MailScanner] section of <avast>\data\avast4.ini:
Log=20
Then generate some traffic, simulate the problem (i.e. force the avast mail scanner to time out by sending an email with attachment) and then post here the contents of the file <avast>\data\log\aswMaiSv.log

hi, I have made the testing as suggested by you, here are the results from the file <avast>\data\log\aswMaiSv.log (a little long, sorry ...)
I am wondering why AVAST tries to connect to 192.168.0.127:110, 127.0.0.1:110, etc., instead of the the ISP POP server 195.34.133.11 ???
Best regards, Erich

This may actually be related to your router, and the changes implemented to the Vista TCP/IP stack.

Please try the following:

  • Click Start>All Programs>Accessories>Command Prompt
  • Right-click on command prompt
  • Click Run As Administrator
  • Type the following: netsh int tcp set global autotuninglevel=disabled
  • Press Enter
  • Restart your computer

Thanks
