Thank you for your help, but it seems that there are still issues with my computer. Deckard's System Scanner still hangs and gives an error message at the "Backing Up Registry Hives" step (I once saw it get to the next step, "Cleaning Temporary Files," but it immediately closed at that point, and it has not gotten to that point again). My Computer displays a flashlight (which I take to mean that it is looking for the location of My Computer) when I click on the desktop icon, and only displays the contents of My Computer after approximately two to three minutes of the flashlight. And it still has a general sluggish feeling. It's almost 5 years old (with a couple of virus-induced hardware refreshes), and my eternally-speedy Powerbook G4 may have skewed my perceptions of speed, but I can't help but feel that the computer is still not quite right.
Though it seems that my problems are not malware related, do you have any suggestions for steps to take to find a remedy? The "Send To" option on the right-click menu still hangs for a very long time whenever it is moused over, could that possible be a result of having the CD/DVD drive as one of the options in that menu (my optical disk drive has been a worthless heap of non-working metal for well over a year)? Again, thanks, and any help you can offer would be appreciated.
EDIT: I have disabled the "Send To" menu since it was never used, but I would think that has only treated the symptom, not the disease.
