Excuse my, it is a translation from the computer.
I have CIS_3.13.125300.577_XP_Vista_x32
What volume have of updating of this program to 2010.01.15? I have already almost 300 Mb, I do not see the end : - (

What are you trying to update? The program or the AV?

The latest version of the program is 3.13.blabla.581. You can use the program updater under Miscellaneous → Update. Or you can do a clean install using the installer of 581: COMODO Internet Security 3.13.126709.581 Released.

When doing a clean install first export your active configuration to a folder that is not part of the CIS installation folder. To do so go to Miscellaneous → Manage My Configurations → select and export the active config. You can import that after the install.

Uninstall CIS, reboot and use this clean up tool to be sure you start with a clean slate.

Now install again and after rebooting you can import your previous configuration.

Please don’t start multiple topics for one problem. It is unnecessary and part of forums experience is simply waiting. When you had no reply within 24 hrs you can “bump” the topic to keep the forums attention to it. I deleted your other topic.
