Re: Chicago 1930 reported as virus by multiple AVs
I'll weigh in on this one because I haven't already: Yes, by all 14...
Note the contents of the names, "Generic", "gen", "Heur", one of them calls it "Riskware", one says "LooksLike", one says "Suspicious" - none of them give a specific name. This means that behaviour of the file (e.g. it is encrypted, or "obfuscated" (note "obfusc" in names), it phones home) is being tagged, not the file itself.
With this knowledge, it is possible to make an informed decision; in this case, it should be that you are safe, as Metaboli checks their own files and "only" a third came up with issues. If it were a named virus, or more than 50% came up with a generic virus, then I would be more cautious.
That said, yes, it would be a good idea for Meta to contact the AV providers to see if their systems can be upgraded; not all of them will listen or take any notice, however, so you still need to use a little brainpower when it comes to generic hits.
