I'm writing this post on behalf of a friend in another state. We keep in contact via e-mail and he has notified me that his computer running XP Home is looking for a file on boot up, behaving eratically and running slow. Since his machine is malfunctioning, I agreed to post a question for him here at Toms Hardware. Here is the error messages he is receiving on boot up: "windows cannot find'c:\windows\system 32\un32info.exe'. Make sure you typed the name correctly, and then try again to search for the file, click the start button, then click search". After clicking OK to the above warning, he then receives the following message: "could not load or run'c\windows\system 32\un32info.exe' specified in the registry. Make sure the file exists on your computer or remove the reference to it in the registry". My friend is a novice computer user, and I'm not sure exactly what he did to cause this problem. He also states the there is a reference to the file in the control panel-add/remove programs list, but it is uninstalled(?). I don't know why it would be in the add remove programs list, it sounds like a part of the O.S. I had him download, install, and run a spyware scanner but the problem persisits. I also suggested he do a complete virus scan, which he says he will do next. Any ideas on what's going on? Is there a fix? Thanks for any help!
