Comodo blocks websites/messenger [RESOLVED]

I have no idea why this happened. I’ve been using V3 for quite some time now, and I’ve blocked web messengers (dont ask why) by entering the address in the ‘hosts’ section in ‘My Blocked Network Zones’. It was all fine. Yesterday I had to block the Frienster site as well, so I entered ‘’ into the hosts section. The internet still worked then.

Today I logged on and found that some websites and Windows Live Messenger are blocked. I couldn’t log into my messenger, nor could I access certain websites like google and even this forum. I checked the Firewall Events and saw msnmsgr.exe listed multiple times, and under ‘Action’ it was ‘blocked’. Also I see ‘svchost.exe’ listed as well, also ‘blocked’.

I changed the Firewall Security Settings to ‘disabled’ and everything works again. Any level above this and certain sites are blocked.

This actually happened once before, when I was adding the web messenger addresses to the block zones. Something similar to now happened and I used system restore, back to a day earlier, and everything worked again. I then proceeded to enter the web messenger addresses again to no problems.

My settings are:
Firewall Security Level - Safe Mode (now disabled of course)
Defense+ - Training Mode
And a whole bunch of web messenger addresses under ‘My Blocked Network Zones’

Everything else is default I think.

I’m using:
Windows XP Professional
Firefox 3.0

Dont keep D+ in training mode all the time. Since you use Firefox then why not use this handy little plug in. I never use a firewall or av to block sites. All web browsers can do that job.

As Vette said before, Don’t keep D+ In training mode all the time, It will treat every application as a safe and will remember, Whether it be good or bad.

As for the messenger. What I don’t understand is why are you trying to block msn messenger? Why not simply uninstall it?

Can you please give me the names of the sites you blocked? - and what was the other site?
I will try it myself and see the results

Hmm, why cant I keep it in Training Mode? I apologize, I’m no good at computers. ;D

I would use that plugin, but the blocked websites are for my sister (mom asked me to block them), and so if I install the extension in my firefox profile, it wont apply to her profile, and I dont have access to hers.

Also, I notice that Comodo sometimes hangs or lags. Right clicking on the icons in the tray doesnt do anything, and sometimes when I edit a setting (a msll setting, nothing big) and click ‘apply’ it lags and takes about a few minutes for it to resume.

Please read the help file. Training mode is only a temporary mode. When under training mode all programs will be trusted including viruses if you have any or get infected. Set your sister up on a LUA. (limited user account). How old is she?. So basically you are trying to block your sister from accessing certain sites correct? Firefox should be the same for each user. Have you tried installing that plugin? There are tons of other plugins also.

Paranoid Mode: This is the highest security level setting and means that Defense+ will monitor and control all executable files apart from those that you have deemed safe. The firewall will not attempt to learn the behavior of any applications - even those applications on the Comodo safe list. and will only use your configuration settings to filter critical system activity. Similarly, the firewall will not automatically create ‘Allow’ rules for any executables - although you still have the option to treat an application as ‘Trusted’ at the Defense+ alert. Choosing this option will generate the most amount of Defense+ alerts and is recommended for advanced users that require complete awareness of activity on their system.

Safe Mode: While monitoring critical system activity, the firewall will automatically learn the activity of executables and applications certified as ‘Safe’ by Comodo. It will also automatically create ‘Allow’ rules these activities. For non-certified, unknown, applications, you will receive an alert whenever that application attempts to run. Should you choose, you can add that new application to the safe list by choosing ‘Treat this application as a Trusted Application’ at the alert. This will instruct the firewall not to generate an alert the next time it runs. If your machine is not new or known to be free of malware and other threats as in ‘Clean PC Mode’ then Safe Mode’ is recommended setting for most users - combining the highest levels of security with an easy-to-manage number of Defense+ alerts.

Clean PC Mode: From the time you set the slider to ‘Clean PC Mode’, Defense+ will learn the activities of the applications currently installed on the computer while all new executables introduced to the system are monitored and controlled. This patent-pending mode of operation is the recommended option on a new computer or one that the user knows to be clean of malware and other threats. From this point onwards Defense+ will alert the user whenever a new, unrecognized application is being installed. In this mode, the files in ‘My Pending Files’ are excluded from being considered as clean and are monitored and controlled.

‘Installation Mode: Installer applications and updaters may need to execute other processes in order to run effectively. These are called ‘Child Processes’. In ‘Paranoid’, Safe’ and ‘Clean PC modes’, Defense+ would raise an alert every time these child processes attempted to execute because they have no access rights. Whilst in one of these 3 modes, Comodo Firewall Pro will make it easy to install new applications that you trust by offering you the opportunity to temporarily engage ‘Installation Mode’ - which will temporarily bestow these child processes with the same access rights as the parent process - so allowing the installation to proceed without the usual alerts.

If you are installing a new, unknown application. Defense+ will alert you with a pop-up notification and, as you want to allow this application to continue installing, you should select ‘Treat this application as an Installer or Updater’ at the Defense+ alert. You will subsequently see the following:

If you need to know, I block them as per my mom’s request as my sister who is still young has been chatting with unknown people on the net.

I have a big list of the websites.

And thanks Vettetech for the explanation. Maybe I should try doing a full reinstall of Comodo?

Why reinstall if its working properly. Are you sure your sister didn’t figure out how to unblock those sites in Comodo. Why don’t you just have her log on and add that plug in to Firefox and password it.

She’s against blocking them, haha. So she wouldnt allow me to get into her profile and block them. I set a password for Comodo, so she wont be able to edit the settings.

Anyway I reinstalled Comodo. The internet is fine now, and I haven’t added any sites to the block list yet. Both are in Safe Mode now.
