Comodo Firewall logs modified?

I’ve been using Comodo Firewall for about 18 months with no problems. However, I have just started to use the Total Uninstall v4.10 utility. After installing ArtIcons Pro v5.19, using Total Uninstall, I noticed that during the installation the Comodo Firewall logs had been modified (see screenshot). Also when I tried to connect to the internet I received the following alert; ArtIcons Pro.exe has modified the User interface of the Parent explorer.exe by sending special Windows messages etc. Unless I allow this, which I don’t, I am unable to connect at all. Any help would be much appreciated.
