When install Comodo , my internet connection slow

When install Comodo firewall , my internet connection is very slow , why ? What can I do for this problem ?

My connection is ok…

But, problem when different connections.

When downloading… my browser does not respond and just loading…loading…loading. But my downloads are normal.

When the downloads are completed / stop all the downloading, then browsing is fast.

Whts the problem??

I third this! My browser loads fine… and utorrent works normal after I did the configurations given here … but the other general downloads have slowed down like crazy!

I’m getting download speeds only around 5KB/s in firefox!! Help!
