Qihoo has many servers abroad in countries like the one you mentioned, US, Taiwan, etc. It probably checks each server and uses the one best to suit your geo location. You can see how many it connects to just by using something like Glasswire Firewall. Malwarebytes web blocking is overly aggressive in my opinion and the IP can be added to exclusions list. Bangladesh was one of the countries it connected to for updating when I tested it with Glasswire Firewall (it's recommended by Qihoo so I just used it).
