Bitdefender Antivirus 2020 gives threat notification

My Bitdefender 2020 antivirus is going crazy every time I start my mudfish program, entering my username and password, and connecting to mudfish server.

This is what the virus report says : Threat Blocked - Item was deleted : threat name : JS:Trojan Cryxos.3793. Path: C:\Users\Sanus\Appdata\Local\Mozilla\Firefox\Profiles\39q659kv.default\cache2\entries\7A40A9BB8625E9CE16B5B6F248C9C1BF17785660=>(REMOVED_NULLS)=>(INFECTED_JS)

How could it be reproducible?
Everytime I start the mudfish program, entering my login username and password.

Edit : I have tried to use different browser; google chrome and my bitdefender antivirus doesn’t give me that threat report every time I open mudfish to login / entering my username + password. Is this an issue with the firefox or mudfish?

Frankly I don’t know. Might be a false positive in my opinion. Please check https://www.bitdefender.com/consumer/support/answer/28557/ and try to disable some modules. Might be this issue is related with “ONLINE THREAT PREVENTION” module in my opinion.
