I use Comodo Internet Security and while updating my Flash player, the process gtbcheck.exe was flagged by the Behaviour Blocker/auto-sandbox as suspicious or unknown and was isolated. The updating appears to have worked but I wonder what this process is.
I believe the gtb stands for Google Tool Bar. The gtbcheck runs during updating or installing Adobe Flash and checks for the presence of the toolbar. If you have not deselected the option to install the Chrome Browser and the toolbar, they will be installed if not already present. Is this accurate?
I always deselect the option myself since I don't want Chrome or the toolbar.
Yes it is a check to see if you have Google Toolbar (a nasty piece of software - I never use it myself).

They will always have the latest Flash Player builds and NO bundled software. Whenever you see an "update" notice, download the installer from the link(s) and run it (them) offline to update. MUCH safer and hassle free.
