VMware shared folders slowed down after installing COMODO firewall

I’ve installed COMODO Firewall 4.1 without COMODO Anti-Virus and Defense+ on virtual machine running XP SP2 inside VMware Player 3.1. After that file transfer speed between VMware Shared Folders and guest slowed down. Is there any fix for this except unninstalling COMODO? I’ve already tried reinstalling VMware Tools but uninstalling COMODO for now is only way to restore normal Shared Folders performance.

Try disabling “Block fragmented IP Datagrams” under Firewall Behaviour Settings → Advanced.

Transfer speed is now much higher altough is not like the without CFW but anyway thanks a lot. I still wonder why is it slowing because it is not shared folder on network.
