The free versios of:
MalwareByte's AntiMalware (MBAM)
SuperAntiSpyware (SAS)

Already mentioned in a reply by David H. Lipman.
Just wanted to second that.
The above free programs are excellent and will find and remove malware and
spyware without any cost.
Report back on the results.
PS: Download, install, update and then run one until it has finished
removing the problem.
MBAM runs best in Normal Windows
SAS 'sometimes' needs to be run in SafeMode to finish certain infections
