If you’re a properly inculcated PC user, you probably always run virus software and, at least occasionally, also ad-ware or spy-ware checkers such as Ad-Aware. Or maybe the PC seems to be running slow, so you check out what tasks are running. The problem is that sometimes something shows up that you don’t recognize, like msimn.exe. It may not be a problem, but it’s a research project to figure out if it’s a program that should be there or not. Many Google links just go to places that have a one line description of the task or program, and the rest of the page is trying to get you to buy their software if you want to know more.

This one has a bit more info, and I like the name of the place: www.AnswersThatWork.com

They’re still selling, but their free answers are more complete than other sites I’ve been to. I include it here because it is usually buried deep in all the less-useful Google listing.
