Not knowing how to repair something can result in a form of learned helplessness, a belief that you are less of something than someone else.

There are efforts to show people that they don't need to buy a new computer, or install software that intentionally limits what their computer can do, or pretends to fix it for a fee. Even the programs that actually work to remove these kinds of threats (including AdAware and SD Search and Destroy) can blur the distinction between actions that are necessary to repair the problem and things that are a different kind of nuisance but not directly a threat to the operation of the computer (like tracking cookies). Software that makes installing it to use it optional is preferred, as the ongoing monitoring can often tax the computer as badly as the software being removed. (Note I'm talking only about anti-adware software here, not general anti-virus software.)

I would love to give a better option than re-install your operating system all of your software, and even that is often a difficult option since the re-installation mediums aren't even shipped with the computer in many cases. I don't want to direct a person to a service where they take the computer to be fixed that often charges more than seems fair for the hands-off approach they take to re-imaging.

Oh, on your last part, I've encountered more than one laptop where all of the installed browsers had been limited to a fraction of the screen being readable due to the number of toolbars, and general search engines being inaccessible or unusable due to the number of injection adds and popups.
