This morning when my computer booted up, the Windows Installer launched and began to install "XMPDLIB.exe". Wary of spyware, etc., I cancelled the install. When I search on Google, et al, I cannot find a single mention of this file. I would think if it were an auto-update from Windows, there'd be some mention of it somewhere.
I had not been in the middle of installing anything when I shut down. I had chosen to hard-reboot (using the power button) because my computer had become unresponsive during normal operation. My son had been using my computer earlier in the evening to look for PSP cheat codes on a site called "gamespot.com", which is why I was especially concerned about some kind of drive-by malware install. But it's strange that there's not a single instance of that file anywhere on the internet that I can find. For what it's worth, that web site came up clean on my SiteAdvisor.
BTW, the system is WinXP Pro with both IE and FireFox installed, so I'm not sure which my son was using. FF is the default but I may have had an IE window open that he used... if that even matters.
Any help is appreciated. Thanks!
