Sorry I initally had retyped the code to replace some variables to make
it more clear, I already had them as raw strings:

import os
pstr = r'"c:\Program Files\Grisoft\AVG Free\avgscan.exe" "c:\program
files\temp1\test1.txt"'
a = os.popen(pstr)
print a.read()

I've confirmed the string I'm inputting to os.popen is EXACTLY the same
as the one I can successfully execute manually in command prompt, so
when I go:
print pstr, it yields:
"c:\Program Files\Grisoft\AVG Free\avgscan.exe" "c:\program
files\temp1\test1.txt"

The problem remains popen won't execute this line as it does when
inputted manually to command prompt.
