antivirus uninstalled but continues to act...

hello

i have uninstalled the antivirus part, and when i launch the file from the eicar test with the comodo sandbox mode, the antivirus send an alert message and says that it puts the file in quarantine.
when i restore it, it askes for adding or not an exception to the antivirus exception rules :o

when i launch it normally (not in the sandbox) i have not this alert, but when i launch it in the sandbox i have it.

when i uninstalled the antivirus i thought it will not exist at all anymore, for the system AND for the sandbox.

so what can i do to uninstall it completely.?
thanks

You sure it wasn’t a cloud detection when it looked up the file?

can you take a screenshot of the alert you are referring to?
