Possibly. But the issue IMO is that they release things Thursday evening (Arizona time).
Most people are going to do the installs Friday night into Saturday because of that. So when things like this do happen there is nobody at ST even looking at / responding to tickets or reading this community over the weekend.
Considering the fact that there was the upload vulnerability that they had that this fixed it would be nice for someone at ST to be monitoring the tickets / community to at least pop in with either "yeah it's a false positive" or "oops wipe the servers and start again" since a lot of us are probably very twitchy because of the file upload issue.
AND
This one is actually a bit worse then the installer since when the .dll gets detected and removed it stops the mail from working.
I like ST products, I like their support. Heck, I even opened a support ticket Christmas eve to wish them all Happy Holidays. So it's not like I am a disgruntled screaming customer.
But, not having people monitoring things when releases happen is kind of meh.
I know it's a slippery slope since once you have people monitoring things around release weekends it's easy to see people wanting staff around all weekends. That just becomes a setting expectations issue. Up to and including if it's not about the release that just happened it waits till Monday.
