I see all kinds of downloaded programs and add-ins when I am trying to maintain computers for others. I find toolbars, useless programs, and many other things that they simply don't need and that they don't remember installing. For someone that is not very IT savvy, when they see an option to click on "Yes" or "OK" to install a program while browsing, they seem to almost always do it. This can slow down a computer or even infect it with a virus.
How do you handle this? What are some ways that you use to clean up a computer that is not performing as it should?
