Download, install, update and run full scans, in safe mode*, with these programs...
http://www.malwarebytes.org
http://www.superantispyware.com
Then re-start.
If you can't run a scan, go into the scanner's folder and re-name the .exe file to something like 'MyFile.exe' and try in safe mode again. Some malware prevent the execution of anti spy/mal/virus scans by blocking them by name.
*Note: On start up (before Windows loads) keep tapping either F5 or F8 then use arrow keys to highlight 'Safe Mode with networking' click on a user account, enter the password (if you don't know it, there probably isn't one so leave it blank) and hit enter/return.
