You don't have a reliable way of knowing what that naming schema means more than reverse engineering your AV software itself.
Some AVs have the option to dump the malware. Maybe yours does, but it is not likely the case because the regular user would never use that feature and it may be risky.
You can use a tool like: Virustotal
To preprocess your file and get some more insight on what the file is.
VirusTotal it is not a tool just for scanning for malware as one may think. It has a very decent amount of automatic static binary analysis which you may find useful. That tool may throw you the offsets of the regions on which the malware lives, letting you extract it, for example.
Then continue your research with your own tools.
