Very slow computer after installing Comodo Antivirus 1.1

[Guest]

Hi,

I installed and activated Comodo Antivirus 1.1 yesterday evening og activated the on access scanner then the program updated the launchpad program and then asked if the system could be restarted. I answered yes to that and the system restarted.

When my desktop showed up the system began to load my startup programs as usual only this time it was incredible SLOW. After 1 hour and 15 minutes I gave up. I switched off my computer and started it in safe mode and disabled the on access scanner, rebooted but to no avail. I then gave up completely and wanted to remove the Comodo Antivirus program but that is not possible in safe mode. The program has rendered my computer completely useless because everything is very slow.

Can you please help me getting my computer back to normal?

Looking forward to your answer!

Regards,

Hi,

What is your OS? What are your system specs?

Sorry I forgot to mention that.

My computer is a Centrino 1.5 GHz laptop witch 1024 Mb RAM and 128 Mb graphics card.

My OS is Windows XP Pro SP2 with all the recent security updates. The problem started right after I restarted when the program asked me to.

I had experienced similar symptom when un-installed CAV (to re-install).
In my case, after un-installed it, my PC became very slow.
So I shuted down a task which used almost 100% CPU by using task manager.
The task was "svchost.exe" used by "SYSTEM".
And I deleted the CAV files(only e-mail scanner) which could not be un-installed.
Next, I used CCleaner to get registry clean.
After all, I restarted the system, re-installed the CAV.
My system is working well with Comodo applications now.

You can find much more informations in this forums than my reply.
I recommend you to see another topics also.

I hope this will help you.

Hi,

Have you had antivirus programs in the past on this system? If so what ones? It could be a conflict.

Actually, I am using F-Secure Internet Security 2006 with antivirus and firewall which I haven't uninstalled before I installed Comodo Antivirus 1.1.

Maybe that is the problem?

"am using" as in you are stillrunning the F-Secure resident scanning module? Two resident AV scanning modules running concurrently is never a good idea. I believe what happens is that they each are checking the others access of files on startup and this induces the lag. If this is the case, they are merely doing what they are supposed to, they just didn't expect another component was going to do the same job at the same time.

As a test, I would uninstall CAV, reboot and disable the resident portion of F-Secure, reboot, reinstall CAV, reboot and see how long it takes. If you prefer to use the resident portion of F-Secure, simply reverse the above procedure.

If this does fix the issue, can you please repost here, so others know.

Thanks in advance,

Hi panic,

the problem are not the other av programs. The real problem is that CAV's resident portion does not really disable itself when the users checks it (even if it notifies the user that is disabled). And this is the reason of all the conflicts

Still you are asking for trouble having 2 resident antivirus apps on the same machine.

Justin you are right. But I had 2 AV programs installed on my computer for 6 years now without having any problems (of course only one engine is active).

ps. by resolving this problem I think that a lot more of people will be willing to test (even partially) CAV. Plus if the other aV cautches a malware it will be very easy to upload it to comodo including the description of the other program.

Exactly how I've been doing it. CAV active and AVG inactive but installed. What CAV doesn't trap, CPF and AVG pick up and then its submitted using CAV.

Well, I solved my problem. I guess the problem WAS caused by having two AV products installed at the same time.

I started my computer in safe mode, ran services.msc, disabled the CAV service and rebooted my computer. My computer was back to normal with my F-Secure Internet Security 2006 still installed.

I will in the coming weekend uninstall F-Secure and install Comodos Anitivirus and Firewall instead. I will report back with how it goes.

Hi panic,
could you please test the opposite? AVG active and CAV inactive? How it performs?

No, I don't like crashes!

LOL.

The resident component of CAV is a bit of a pig to get turned off fully and re-enabling it isn't much easier. I've tried it the other way round and have found that the best way is to disable the resident component of the non-Comodo AV app and leave CAV's resident component turned on.
