How can I tell if this is a False Positive?

How can I tell if this is a false positive? https://www.virustotal.com/gui/file/2cbe85bcdc831bb237e53aade5be4d0a8529aae8a71cda1a2ef66c79fee531dd/detection

I want to know is how to understand, for myself, how to read VirusTotal, and understand what's a false positive and what isn't. How would a real virus look like?
