If you can run Biber successfully from the command line, then neither
Biber nor Perl can be corrupted.  Emacs actually doesn't do anything
else than invoking programs on the command line.

If things don't work with TeXworks or WinEdt, please look into their
configuration files.  Maybe they are not consistent.

It's unlikely that there's something wrong with your environment since
programs work on the command line.  But it can't hurt to check it
though, just to be sure.  Type

  set > environment.txt

on the command line and inspect the file carefully.  TeX related
things are suspicious.

It's certainly not a Perl problem either.  You could update many files 
but not updmap-sys.  I still suspect file permission problems.  Please
note that what has been discussed recently is *not* related to virus
scanners only.  Any program can lock files needed by other programs on
Windows and make them crash.

However, if it happens again, please save the error message before
doing anything else.
