Press the button "Do a system scan and save a logfile", after that you will see a list of items with chechkboxes and a log opened in you default editor (e.g. notepad). Further you have to get known, which items are "bad" (spyware, adware, worms or viruses). For example, you can place your log at this forum and ask people to analize it. After that check the processes that you want to get rid of and press the button "Fix checked". Thats it!
