OK, I’ve been tested (human time meter)
The DNS Resolution request started at 5-minute intervals (After DNS Resolution Completed)
1hr=12 times, 1day=288 times, 1year=100880 times

Yes. I verified this. It happens when cloud scanning is enabled. It is trying to connect comodo to get the delteted vendor list. But it is supposed to do so every 3 hours not 5 minutes. Bug is verified and be fixed before the update.

But, I don’t use any cloud service. :-[

For testing purposes, can you please change BLOK and LOG rule to ALLOW and LOG and see where it connects?

This will help me to identify whcih service is repsonsible for the requests.

Thanks,
