Does anyone else have this file on their computers in an uninfected state? - File is not here.
Am I right in assuming that if i place a file in the recycle bin and WindowsXP ght?seems to be loading and running ok to me then the file is not needed to run the system? - Yes.
What I'm trying to say is if windows needs a file to load it wouldn't look in the recycle bin, right? - Yes.
