Yesterday, after the update to the new version, I noticed, like many people here, that the taskbar icon doesn’t appear anymore when booting the OS. But in my case, it cannot be an OS bug since I use Windows 7, and not Windows XP. Furthermore, I’m using Comodo Firewall for 5 years now, and this never happened before, not even on XP. The software is still running but I’m so used to see the icon there that I miss it.
Try Right clicking the start orb and select properties->Choose Taskbar, then Notification Area->Customize. Is Comodo Internet Security Premium in the list? If so from the dropdown select “Show icon and notifications” and hit OK/Apply.
It’s not that problem either, because, not only Comodo is in the list, but I also have the option “Always show all icons and notifications on the taskbar” checked.
