I assume this is not a false positive.
I ended up doing a factory reset and finally the malware alert does not appear aymore. I didn't find another solution and I needed to be fast becaue someone managed to order some stuff from my amazon account to an adress 400km far away from me.
There has been an influx of texts and calls from "amazon" claiming you've had a charge for a large amount of money. They are phishing attempts.
If you clicked any of the text links or pressed1 to speak with an Amazon rep, file a security report with Amazon and file a police report, change your passwords (email, amazon, bank), enable 2 step verification on Amazon and bank apps, and call your bank.
For the record I got these but never clicked links or pressed 1 on phone call.
