Norton 360 Flagged Ableton 12 as Malware—What Should I Do?

It sounds to me like you might just be dealing with a false positive. This can happen sometimes with antivirus software, especially when you're downloading software that isn't as widely recognized. You can check if it's a false alarm by looking up 'Ableton 12 false positive' online. Also, using a site like VirusTotal to scan the file can give you peace of mind as it uses multiple antivirus engines to check for issues.

In my experience, uninstalling Norton can sometimes be the best remedy for situations like this. There's a lot of chatter about Norton being more of a hindrance than a help at times. If you want to be super cautious, just run a scan with Windows Defender after uninstalling Norton.

Honestly, I would recommend checking into alternatives. Norton has a reputation for being overly aggressive with its alerts, often flagging legitimate software as malicious. Consider uninstalling Norton and using Windows Defender instead, which is free and usually effective. It's not uncommon for Norton to induce unnecessary panic.
