Step 4: Downloading Tools

Download the following tools and save in your favorite download folder or create one, for example C:\Spyware Tools or C:\Downloads. ( It is not a good idea to download them to any folder within C:\Documents and Settings.) And then install, update, and configure as indicated below.
Do not run the scans until later when indicated.
CCleaner(click on link) CCleaner
Install only, then exit. We will run tools later. MAKE SURE you uncheck the option to install the Yahoo Toolbar when installing CCleaner. We do not want ot install any unnecessary baggage. It will install by default unless unchecked.
Also it is recommended to login to any other User Accounts on the Computer and run CCleaner on each on.
Ad-Aware SE (click on link) Ad-Aware SE
Install, click Check for Updates now and get any updates, then exit.
SpyBot - Search & Destroy(click on link) SpyBot - Search & Destroy
PLEASE leave all settings at default!!!! Install, do the search for updates now and get any updates, then fix the below problem with Spybot default products. If you get an error message about "bad checksum" when trying to update, just choose a different server location. Also look for the Immunize feature in Spybot and use it. Do not use the Teatimer function. It can be a resource hog and also makes removal of certain problems more difficult. Make sure you leave the SDhelper ( IE bad download blocker) checked to install (this is the default).Fixing SpyBot's Ignore Products Bug: Please run SpyBot and get into the Advanced mode by selecting Mode and then Advanced mode. Then select Settings and the in the left column select Ignore Products. In the right window pane make sure the All products tab is selected. Then in that window, right click your mouse and choose "Deselect all". Now exit Spybot. We will run a scan later.
