I have just installed CAVS on my system, along with the Comodo Firewall. I have an AMD AthlonXP 3200 and 1Gb RAM and use Eudora7 for my email.
When email is being read, my system now gives the impression of freezing as CAVS takes over all resources and spends an inordinate amount of time processing mail. When I disable email scanning it returns to normal (and if I do this incrementally, CAVS feature by CAVS feature, it improves a little each time).
What should I do?
The email scanner gets loaded when you first time email client checks the mails. So first time it may take some extra time for email scanner initialization (approax 10-15 second). But from next time it should not take these extra time and should be faster.
Does email scanner scanner works fine(without unexpected delay) from second email download and onward?
Unfortunately the only thing that returns my my system to a stage where it is not (equally) affected by system slowdown during email reads is completely turning off the email scanning feature of CAVS.
It is an easy explanation to make, but previously I had NAV 2003 loaded but before I installed CAVS I unistalled NAV (tediously) including many searches and regedit deletes with restarts between each step. There is a possibility that something that CAVS shares amy have been deleted I guess but I know not what.
Hard to say.
I know CAV with Outlook 2003 is not a fast experience either. So I am looking forward to CAV Beta 2.0.
What I suggest is opening the task manager and sort by CPU usage. What you will probably find is that when you are going to download your e-mails CavEmSrv.exe pins your CPU at or near 100%. If that’s the case, I’d your install is fine and that CavEmSrv.exe is still in Beta with the rest of CAV.
Thank you for reporting your problem, it can only help the developers to know where more work may need to be done before CAV is officially released.

I just installed Comodo AV. I use PocoMail 4.1 and have the same problem, the system will just seem to lock up. After about 10 to 15 seconds it will respond some.
I checked CPU usage in Task Manager and CAV Email Scanner is using 99 to 100 %
Turning off email scanner and everything seems fine.
DO you have CPF installed? If yes, which version of CPF you have installed? We had this problem with CPF v 2.0 and the bug was fixed in CPF v2.1 version. Just for testing, you can uninstall CPF, reboot and check your mails again.

When I was running Comodo Anti-Virus I had the latest Beta CPF running. I had to uninstall CAV and go back to Avast. Things were just to slow with CAV running. I will give CAV another try when beta 2.0 comes out.
OK. We all recognise that CavEmSrv.exe is pegging the CPU (OE 6.0 used here).
Is there a bug track on this problem? Does Comodo need any diagnostic traces to confirm the problem and/or fix?
Been tracking this down…
CavEmSrv.exe appears to stall when the headers of e-mail message, and generally ca. 26000 bytes long, in question look like these examples :

This is not a CAVS problem with scanning e-mail headers.
The MimeOLE 6.00.2900.2180 code fails to build a compliant string for its signature -
X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2180
…where the string termination should be 0x0D0A0D0A but is 0x0D0A0A.
Wherein the scanner in OE6 loops when searching the results of a TOP x 0 POP3 command.
NB The messages are scanned whilst on the POP3 server and not after the RETR x POP3 command downloads the messages to the POP3 client. Scanning after downloading works successfully.
