Thanks for that twl845, I am have been using CPF but wanted to give OA a try. I was a little concerned about the resident shields as I have Avast Pro installed at the moment but think I will do what you did and use the free version first and take it from there. The reason I wanted a change is that I have never been 100% with CPF and the new version is somewhat daunting! Thanks BL

Thanks for that twl845 and yes I think I will go along those lines. Maybe daunting was the wrong word to use but I did find CPF somewhat time consuming at first unless you want to use it 'out of the box' a bit heavy going for a home use firewall for me. So the new version of CPF and all the problems people have had with it put me off! Thanks again. BL

After i had unplugged and then plugged in my external DVD drive, none of my applications would start up. I jsut got the message, "XXXXXX is not a valid WIN 32 application". Okay, so i wnet into safe mode and did all the scans i could think of, nothing. tried to play around with the msconfig, nothing. Then i remembered i made a little mistake when one of Comodo's application warnings came up. Anyhow, i will un-install it tonight and see what happens, i dont't see it being anything else. Ever since i installed this firewall, i have jsut been annoyed with it - jsut as i was with Kaspersky. If these companies serioulsy want to get into the home and home-office market, then they really should make things a little easier. they ahve way to many user-rights controls and it just gets annoying when you have all these pop-ups. I will be going back to Windows firewall, which works just fine for me. Hopefully takeing COMOD off will resolve the problem. If not, i don't know what to do next

Hi Optimizer and welcome to CastleCops. It's your choice if you decide to revert back to the Windows Firewall but remember that it is a basic firewall that only gives incoming protection.

I have used Comodo and yes it can be a little daunting at first but you can use Comodo and most other firewalls 'out of the box' so to speak.

Which version of Comodo did you install? If it was v3 then I would suggest you try the earlier version 2 and also remember that you can check the box on the pop ups to remember your decision on so reduce the number of pop ups that you get.

Have a look at the following which covers FAQ's with regards to the installation/how to use procedures.

Thanks for your help. I downloaded it from CNet, so i would imagine it was the latest version. Anyhow, i went into safe mode last night and uninstalled it and now my system is running fine. Yeah, windows firewall is basic, but it does the job. I have AVG also, combined with some antispyware programs. I always give my pc a good sweep each week and have not come across anything major. I have had the same PC for 5 years now and it runs jsut as good as the day it came out of the box. I don't think i will go back to COMODO again though.

Okay, thanks:) i will check it out:)
