KAV 5 problem with firewalls

[Chuck57]

I downloaded the latest version of Kaspersky 5 Personal antivirus a couple of days ago and immediately ran into a problem. It somehow managed to block access to the Internet with every firewall I tried.

I had McAfee's newest firewall installed and couldn't access the Internet using either Firefox or MSIE. Thinking maybe it was a firewall problem, I switched to ZA Pro and got the same thing. I couldn't get to any sites with either Firefox or MSIE. I even tried my Visnetic 2.2.6 and couldn't open any sites, and LooknStop and Sygate Pro. Same problem with all of them.

Finally, it occurred to me that the only change on my system was KAV 5 Personal. I removed it, rebooted, and everything worked again. Has anyone else experienced this problem and do you know what happened. I tried everything I could think of and never managed to fix whatever happened. Wish I'd kept the firewall log entries but that didn't occur to me either.

Just curious. Anyway, I'm back with McAfee's new firewall using AVAST again and all is well.

Thats because of the "minifirewall/IDS" in Kaspersky 5.0 Personal & Pro, you need to disable it during the install:

You will during the install encounter this window:

Here you uncheck "Operate according to recommended settings", click next and proceed to the next window:

Here you uncheck "Use real-time protection against network attacks", click next and finish the install as you would normally do.

Important: IDS is a part of the firewall, and it cannot replace a fully functional firewall on your computer. Kaspersky Labs recommends you to use this system (Intrusion Detection System) only if you do not have a personal firewall on your PC. In order to have full control over network activity on your computer (control over applications' network activities, packet filtering) we recommend to use a fully functional personal firewall:)
