When I bootup my computer I have two messages that pop up about some part of my firewall not loading. I can click OK and they go away but my firewall does not not start. I then can click on the icon and the firewall seems to load and perform well.
Open Comodo and go to the Sumaary and check System Status. When it is not ok let it do it’s thing to try to solve it.
Take a look at https://forums.comodo.com/empty-t17615.0.html . StartRight seems to help cure some of these types of problems for XP users.
There are probably a dozen threads on this board related to this problem. Search for cfpres.dll, they will all come up. I really hope Comodo gets this fixed. It happened to me again today.
