comodo antivirus stops working at 11%

For the past 3 years I have been using Comodo CIS as my firewall, but have stopped using the antivirus program because it stops working at 11% complete status. This happens no matter what file it is scanning at that time. This seems to be a limit. I use another antivirus software and it has no problem with all my harddisks.
I have an old Pentium 4 2.8Ghz with 1G memory, 3 internal (32G,1Tb,40G) and 1 USB (1Tb backup) harddisks. It seems that the antivirus software freezes at 11% scan when trying to scan the full system. Which is the default scan and that I do not want.
Is there some way of scanning my whole system but scan each harddisk at different times? So as to complete a full system scan.

I am using Comodo Internet Security Premium
Product Version: 5.12.256249.2599
Virus Signature Database Version: 14468
Operating System: Windows XP sp3 fully updated

Thanks for any help.

Hi stantheman1,
To scan individual disks could be set up through creating individual profiles for each location.
Scan Profiles

These scan profiles could then be run manually or set up individually through scheduled scans to be run a different times.
Scheduled scans

Edit: Right clicking on individual drives will also give the option to scan each one manually.

Thanks very much for your issue report. We have moved it to the non-format bugs board for the moment, because too much of the information we normally need to replicate a problem and fix it is missing, or it is not in the format we request.

We realize some people may not have the time to do bug report in standard format, and therefore offer the option of a non-format report instead. But the problem is much more likely to be fixed promptly if you edit your first post to create an issue report which meets all criteria in the Checklist and Format. (You can copy and paste the format from this topic). The general reasons why are summarized in that post, the reasons we ask for specific pieces of information are given in this detailed post.

You can get your report moved to the format verified issues board simply by ensuring that it is correctly formatted and all criteria are met, and PM’ing a mod who is active on the bug board.
