Avast 19.5.2378 (build 19.5.4444.537) accessing my internal website, why?

Checked my Apache access logs and found
ip of machine with Avast- - [19/Oct/2019:11:01:49 -0400] “GET / HTTP/1.1” 302 480 “-” “avast! Antivirus”

    • [19/Oct/2019:11:01:49 -0400] “GET / HTTP/1.1” 401 2532 “-” “avast! Antivirus”
    • [19/Oct/2019:11:01:50 -0400] “GET /HNAP1/ HTTP/1.1” 302 511 “-” “avast! Antivirus”
    • [19/Oct/2019:11:01:51 -0400] “GET /HNAP1/ HTTP/1.1” 401 2564 “-” “avast! Antivirus”
      redirected to HTTPS and blocked due to password protection.

Question is why is Avast trying to hack my web server with Home Network Administration Protocol.
HNAP1 is a problem and should not be used.
Is it really intrusion testing it for me? I would be impressed if this is the case

Avast checks every part of your network.
