Solved has shown up on one of my XPPro SP2 machines on the root drive:  The Microsoft Visual C++ Redistributable Package.  I did not install this.  Can anyone tell me how it shows up on a machine?

I have a very recent build of XP Pro with SP2, all updates, Firefox 3.08 w/NoScript, Sandboxie, Google Earth, latest Wireshark, latest Nmap, Comcast's version of McAffe Security Center, TCPView, Process Explorer, latest Thunderbird.  Machine is on its own IP behind a Netscreen 5XP.  I just recently noticed the and its files while looking around in Windows Explorer.  I know for sure that it wasn't there upon completion of the new ground-up rebuild.  Any feedback would be appreciated.

Download details: Visual C++ 2008 Redistributable Package (x86)

Microsoft Visual C++ 2005 SP1 Redistributable Package (x86)

Probably came from here, and maybe packaged from one of your other apps that needed it?

  Thanks for the response.  Is this a common practice with various software apps to do this as part of an install, to your knowledge?  Can you think of an example of apps that do this?  I guess my main nervousness is that I hope it is not part of somthing malicious.

I dont have any off teh top of my head, for example purposes. Depends on how the app is written/packaged. Sometmes they can download the needed dependencies, and extract them, but usually it is done to a TEMP folder.

If you right click the file>Details, is it signed by MS?

johnb6767,  I retraced my steps installing the mentioned software on another clean build XP Pro, and found that it was NMAP install that used and its files.  All is well.  Thanks for steering me in the right direction.
