A/V Database Update slow

New update (database ver 1341) took about 8 minutes.  Still long compared to other antiviruses, but much shorter than the previous update.

Update to 1367 took 4-5 minutes.  Might be because I'm getting update notices at shorter intervals.

There were a couple of tolerable updates since the last post, but the latest update (to 1642) again took over 30 minutes of grinding.  In light of this, and the increase in false positive rates lately, I'm uninstalling the antivirus component.  The firewall can stay.

In my opinion, the A/V update process is an absolute disaster - it takes far too long and eats up PC I/O and memory to such an extent that it can lock up a PC for the duration of the update. CIS should not have been released with this obvious design fault.

There have been numerous post related to problems with the A/V update process. Surely if there was a candidate for an emergency upgrade to CIS 3.10, then this is it.

One of the most frustrating and disappointing aspects is that Comodo Support seem to be ignoring the users' plight and have not responded on this matter. They need to admit the widespread problems and propose a solution and a timescale for its implementation.

It seems slow here too. My PC is hardly usable for like 5-10 mins (didn't time exactly) every time Comodo updates. It's not my internet connection; I'm on a blazing fast University connection.

5-10 minutes that's a lot for incremental updates.

I think a lot depends on your PC spec. I've got CIS installed on a variety of platforms and I would say that on a dual core PC with 2GB RAM, there's virtually no impact on performance. One core can handle the CIS update leaving the other free to run your application(s).
It's a different story on a single core PC with only 512MB RAM. Here, everything stops for tea while CIS updates. It's particularly bad if you've not used the PC for a day or two and it needs to add a lot of new AV sigs to the database.
I'm not sure if things improve if you throw more RAM at it but I can say that if you only have 256MB RAM, then it's absoulutely dire - can easily take 10-15mins with lots of disk thrashing and the PC is totally unusable during that time.

CMDAGENT.EXE grows from 1.404KB at idle to 292,472KB while updating. This does put a big strain on resources if you have only 512MB on your XP system. If the updates are incremental, the diff calc and integration must be horrendous.

Yes. I've got 512mb on an old laptop. It's kind of sad, one of the reasons I use Comodo is the lowresource consumption, and I'm quite happy about it, except for the occasional 5-10 mins. I'm  actually in the middle of an update session right now, so I can do things, but it's quite annoying.

I have the latest update, but it takes every day 15 minutes to update the database and it slows down the computer extreamly. Can't you do an intelligent updater, which checks what is downloaded already and downloads only new the datas. I don't belive that it should be a difficult thing and if someone uses the computer every day then the changes in the database should be only some MB which, can be downloaded and modified in 1-2 minutes instead of 15.
