Hi danohi50, it is a notification that comodo dragon does not support that norton add on. The puzzle sign refers to add ons.
Norton is a very complex antivirus software and it is almost intrusive, to me anyway, for example, it will automatically defrag your hard drive unless you disable it from doing so, which is a no no for SSD hard drives.
go to extensions and disable it, click on the Comodo Dragon icon at the top left corner of your screen and hold the cursor over tools , when the second window opens click on extentions and disable it.
hint : use Comodo dragon just for WGT and another browser for everything else and you will continue to have no meter issues.
hope this helps.
