I checked nostr.mom just now and it looks like an ordinary relay:
- Its NIP-11 info is standard: strfry 1.1.3, described as "Spam and nudity filtering. Stricter and more experimental than nos.lol".
- Valid Let's Encrypt certificate for nostr.mom, renewed 22 Sep, expires 21 Dec.
- One IP (142.132.206.70), and the web page answers normally.
Nothing there says why BitDefender flags it, so I won't guess. What name does the alert give? "Phishing", "untrusted website" and a malware name like "Trojan.xxx" mean very different things. If it's a generic reputation warning, it's most likely a false positive. BitDefender takes those reports (URL, category "False Positive") and says it removes wrong website blocks within 72 hours:
