I think you need to contact the anti-virus vendor to get it to write 
more informative reports.  For example, what is the executable in the 
Temp directory?

Sweave by itself runs no executables, you normally run latex or some 
related program on its output; perhaps your script is trying to do that. 
  But diagnosing it without knowing the executable that is being run 
isn't really possible.
