Go to My Computer->Tools/View->Folder Options->View tab and make sure that 'Show hidden files and folders' (or 'Show all files') is enabled. Also make sure that 'Display the contents of system folders' is checked. If you have Windows XP, the search feature is a little different. When you click on 'All files and folders' on the left pane, click on the 'More advanced options' at the bottom. Make sure that 'Search system folders', 'Search hidden files and folders', and 'Search subfolders' are checked.
For the options that you checked/enabled earlier, you may uncheck them after your log is clean. If we ask you to fix a program that you use or want to keep, please post back saying that (we don't know every program that exists, so we may tell you to delete a program that we think is bad to keep).
