Well first it is inadvisable to use ‘the Administrator’ account for routine use as any malware inherits the user privilege and can do virtually anything.
Try SuperAntiSpyware (SAS) as that has a Repair function and one of the options it to repair/Enable the Control Panel, which some malware disabled to make it difficult for you to remove them.
It also wouldn’t hurt to run it either - SUPERantispyware (SAS). On-Demand only in free version.
Don’t worry about reported tracking cookies they are a minor issue and not one of security, allow SAS to deal with them though. - See http://en.wikipedia.org/wiki/HTTP_cookie.
