(found it pretty amusing that Kovid referenced Bruce Schneier's coined "security theater", as I've been reading parts of his writings recently)

if so, I suggest you wait until tomorrow, when there will probably be a new Calibre release, or try running it from source

From that github post:

Windows builds: sign DLLs in addition to EXEs

DLLs signed in addition to EXEs. Because of course, executable code can
only be in DLLs and EXEs. Roll eyes.

I laughed. That's pretty good stuff.
