DoxDesk is more or less a blog with some useful, if pretty techie, info. Now, back to the Spybot thing.
1) Open Spybot, in "Advanced" mode, while you are connected to the internet.
2) Click "Online"
3) Click "Search for Updates", and follow the instructions as they come along.
4) Click "Spybot S&D"
5) Click "Immunize", then click the "Immunize" button on that page, and click "Install" below that in the pane called "Permanently running bad download blocker for Internet Explorer". For now, DO NOT check any of the boxes below that pane, in the "Recommended miscellaneous protections" pane.
6) Disconnect from the internet. Click "Search and Destroy", then click "Check for Problems". Go do something else for a while; your machine will be busy. Of course, you can always just sit there and stare at the screen while stuff goes on.
7) When the process completes, click "Select all items", then click "Fix Problems"
8) When that's done, click "Settings" and in the pane on the left side click "Settings" again. Scroll down to "System Start" and click to put a check in the "Run program once at next system startup" box, and in the "Fix all problems at program start" box.
9) Exit Spybot and reboot your machine. As it is restarting, persistently tap the F8 key ... that will bring you to your boot menu. Select option three, "Safemode". The machine will boot into safemode, and your desktop will probably appear a little funny ... don't worry about it. If the "Windows Help" page comes up, just close it, even if it asks you "Are you sure. You may also see a notice box that you are running in safemode. Just close that, too. Spybot should be running all by itself now, with no distractions.
10) When it is done (again, that could take a while), reboot normally. Just as good practice, run Spybot one more time, after having first thoroughly read its tutorial, which is found under its "Help" button. You should be good to go. You ought to see something like this:
