Hello all, we are aware that Palo Alto Network's Cortex XDR, an "AI"-driven security (aka "anti-virus") application, is hallucinating and is incorrectly claiming @Vivaldi is dangerous. This is a false positive, and we are waiting for them to fix their product.
In the meantime, we are aware that their software apparently provides options for you to exclude Vivaldi from scanning, if your organisation allows it.
