Bitdefender Firewal popup message to block or allow dllhost.exe

Hi,

Bitdefender Firewall popup message is constantly appearing on the screen. It says:

"The application: C\Windows\S...m32\dllhost.exe is sending a TCP (6) packet:

100.127.255.253/0:57923 to

100.96.32.182/0:HTTPS (443)"

I have clicked on button "Block" for 50 times, but it keeps showing.

Could you please help me? Should the dllhost.exe be allowed to send data out?

Thanks.

A
