Ones to look at carefully because the spyware/adware often use them:
BHOs - Browser Helper Objects - IE acts as if it assumes that all BHO's are friendly. Apparently this is a rather easy install to make under the covers.
Search bars and Search assistants (usually a HKLM entry - Local Machine key entry in the registry) Again, an easy install
Toolbars that you did not invite or don't recognize.
Run and runservices entries on programs that you don't recognize.
Ectra tools and menus often can alert you to the fact that something has gotten in.
Plugins are probably the hardest to install under stealth, but are probably the most damaging because these are full blown apps that can take over your whole puter.
