Dozens of emails about new antivirus threats

What is gcc? These aren't system files then, I take it?
I'm currently running the latest firmware - I think it's 6.10 Hotfix 1 or something like that.
I had previously SSH'd into the NAS some years back in preparation for doing some more intensive work - I wanted to try and get a Calibre server up and running - but I never went as far as actually doing anything other than establishing the SSH connection.
One other point - the same threat keeps coming up in the emails - it's called "Heuristic.XZ.DicSizeLimit". This sounds like a very generic/benign threat, where maybe it's being flagged due to an unusually large file size and nothing else. Would that be an accurate read of the situation?

gcc is a C compiler. https://gcc.gnu.org/
What apps are installed on your NAS???
Is your NAS open to the internet (ports forwarded, etc)?

Note it's not installed at all on my system. But I don't think this folder normally contains any executable files.
I think the first question is to figure out what installed it.
