Can AVG antivirus detect PS2 BIOS files as threats?

While setting up my PS2 emulator, I noticed that AVG antivirus flagged my PS2 BIOS file as a potential threat. I’m sure I dumped it from my own console, so I’m wondering — is this a false positive, or is there something else going on?

Has anyone else experienced AVG or other antivirus software mistakenly flagging BIOS files? Any tips on how to safely handle or whitelist them without risking your system?
