First, let me state that this post is not a criticism of Comodo or their products. I sincerely appreciate the work that has gone into CIS and I appreciate the fact that it is made available to us free. This post is made with the intent of helping to provide input on a problem that seems to exist so they can resolve the issue, and it’s my way of paying back in a small way and saying thanks.
I have three computers, two of which are WinXP SP3, one is Win7x64.
I performed the upgrade to CIS a few weeks ago on all three computers due to the AV update problem that was occurring at the beginning of January. I uninstalled CIS and completely reinstalled the new version, then downloaded the AV signatures and copied them to the proper directories.
I began to notice a slowness in my programs opening shortly thereafter on the XP SP3 computers, but hadn’t thought much of it until two days ago both my XP SP3 systems ground to a halt. The systems were very slow to load the desktop icons and when I tried to open Firefox, they both totally ground to a halt.
My Win7x64 laptop has absolutely no problems whatsoever and is extremely fast.
After performing many diagnostic tests with no success, I read on this forum that the AV component of CIS was having issues.
I uninstalled CIS totally from both XP SP3’s and reinstalled CIS without the AV component. I then installed Avira anti-virus. I did not modify the Win7x64 computer.
Both WinXP SP3 computers now load programs faster and run faster than they have for a long time. The results were amazing to both my wife and I.
Apparently the Anti-virus component of the CIS has problems that need to be resolved.
Once again, this is not a criticism, as I realize not everything’s perfect, stuff happens and you folks are trying to do the best you can and I appreciate it. I’m just trying to help you out.
