Yes, this is expected behaviour.
Miqobot uses functions that Anti-Virus softwares find suspicious, and pretty much every game or software use these kinds of functions too, but usually most companies report their programs to the Anti-Virus companies long in advance so they’re not detected as possible threats.
However, AV-companies often take very long to whitelist stuff and it’s often very troublesome, which is why Miqo doesn’t bother with that anymore and people are just instructed to whitelist Miqo, as this behaviour is expected.
