When files/programs are quarantined how do I know which ones to remove and which to restore?

Basically you crawl the web with the related file names tacked on after the word remove and read carefully the information provided by the search engine. Keep in mind that the automatic removal tools rarely do the full job and many things must be removed manually. Often it is better just to pay to get the stuff cleaned up. Especially if you are not comfortable using the registry editor,
