1.
the system is not allowing me to delete one user's Content.IE5 folder...Also, when trying to delete one user's Cookies folder, I get this error...
When I said to delete the entire contents of those folders, I meant just that- delete the files in the folders, not the folders themselves. From what you're asking, it sounds like you're trying to delete the Cookie folders themselves, and Windows won't let you do that (as you found out).
Windows will actually let you delete the Content.IE5 folders entirely (because it will/can automatically create new Content.IE5 folders as needed). If Windows doesn't let you delete entire folders within Content.IE5 or the Content.IE5 folder itself, sometimes you have to go deeper and individually remove the files in those folders first. Windows may then allow you to delete the folder once it is empty. If not, you'll have to identify the actual file that is refusing to be deleted; the files name (or information in its properties) could tell us if it's anything to worry about or not. The folders inside Content.IE5 are ranmdomly named by Windows, so the folder names "Y7EJUTMF" and "YUK0JKTD" that you posted won't really tell us anything useful.
2. Your log shows that you got rid of a couple of the bugs, but not all of them. Are you positive that you entirely deleted the "C:\Program Files\WildTangent" and "C:\Program Files\SurfSideKick 2" folders, as well as the "C:\WINDOWS\wupdt.exe" file? All three still show up in your log.
