The question about the registry value

Hello.
I have Comodo Internet security.
The program works well and stably.
But today, the startup found registry entry:
C:\Windows\temp\chromodo_setup.exe silent –
Previously, this value was not.
Is this normal?

It looks like an entry for the update of Comodo’s Chromodo browser that will install with CIS by default. Check if Chromodo is up to date and remove the entry from the autostarts list. There is no harm; it just looks sloppy.
