Only malware masquerading as Battle.net Launcher should be flagged as a virus. If the file path and signature do not match Blizzard's official installation location, or if the file is unsigned or signed by an unfamiliar publisher, it could be malicious.

How to Verify Legitimacy

Check File Location: Ensure Battle.net Launcher.exe is located at C:\Program Files (x86)\Battle.net\Battle.net Launcher.exe and not in a random download folder.
Verify Digital Signature: Open file properties for C:\Program Files (x86)\Battle.net\Battle.net Launcher.exe and confirm a valid Blizzard Entertainment, Inc. signature; valid signature should show Blizzard as the publisher.
Check File Hash: Compute SHA-256 hash of C:\Program Files (x86)\Battle.net\Battle.net Launcher.exe and compare to Blizzard's published values.
Scan for Malware: Run a malware scan on the launcher directory using Windows Defender or your security suite.
