This is not a TeXworks issue, a better place to ask is the TeX Live
mailing list.

All these files come from TeX Live.  These files are wrappers needed
by TeX Live, not the programs themselves.  The purpose of them is to
launch programs in a modified environment.  PSV, for instance, needs
Ghostscript and the wrapper makes the hidden Ghostscript provided by
TeX Live visible to PSV.  TeXworks has to be told where the files it
needs are located in TeX Live.

These wrappers were updated 2010/02/28 in the TeX Live Subversion
repository indeed.

Thanks for providing them.  I can confirm that they are identically
equal to those calculated from the files in the repository.

Someone else reported the same problem today on the TeX Live mailing
list and Tomek, the author of the wrappers, recommended to report this
problem to Sophos and ask them to fix the scanner. 

I recommend you to report the problem too, I don't know whether the
other person did.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
