Windows Explorer + USB + Comodo

Hello friends:

When I connect a USB hard drive to pc, and then I want to disconnect, I have a Windows utility called “USB Safely Remove,” but sometimes the hard disk can not be disconnected because it is blocked by Windows Explorer (explorer.exe) Then I give the option to unlock and closes the browser windows (temporarily disappearing status bar and the desktop, no windows programs). Later I will appear everything but sometimes in the bar of icons of programs that are loaded with the beginning, Comodo icon disappears, but I see in the Windows Task Manager, which cfp.exe is working.

In short, the icon disappears me the firewall but this is working. How do I upload the start Comodo icon, without having to reboot the PC again?.

Thank you.
