Thanks for the additional information.
What virus scanner do you have installed? Does the problem persist when
you exclude "postgres.exe", the postgres program directory and the
postgres data directory from scanning?

A backtrace of both "stuck" processes would be helpful in determining
what it is that they're up to. As they're stuck in an apparently
infinite loop, taking several samples would be preferable as different
samples will be at different places in whatever loop they're stuck in.
