PC Freezes when sending message with incredimail

Well, I want to thank all for their comments.

I changed the AV from ESET to AVG to now AVAST
on the Dual core 2 machine running Vista Home Premium,
and the lock-up upon sending mail has continued. It does
not matter whether the email client is Incredimail, the built
in Vista client, or outlook 2003 -- they all lock when trying
to send email. So, methinks that it is now time to wipe
and reinstall from scratch on that machine and start anew --
perhaps without Incredimail on that machine.

However, now I have installed 3.0 AV on an older XP machine,
and, out of the box, I cannot send or receive email using IncreiMail
on that machine. There is no lock up or freezing, it just doesn't
receive email, and I have not found a settings change to address
this problem -- I just have to turn the AV off to receive the email.
So, I will try some of the exclusions and other hints offered
by HiTech and others, and see what happens.

I thank you all for your input !!

 

Well, an update....

I have placed the two active exe files in exclusion, those being
ImApp.exe and IncMail.exe. This has been unsuccessful and
I still get the error message:

-ERR AVG POP3 Proxy Server: Cannot connect to the mail server!

I can send email, but not receive off of POP3 accnt.

So, if there is another setting I need to look at, any comments would
be most appreciated !!

{Win XP Pro/NOD32 AV 3.0XX/Kerio Personal Firewall <?>2.14 running
without change both before and after.}

 

Couldn't it be that Kerio FW is blocking POP3 traffic for ekrn.exe? Could you try disabling it for a while so that you can make sure the firewall is the culprit?
