SpyBot is not any good, and i would replace it with malwarebytes or/and superantispyware
Check for malware with this
Malwarebytes Anti-Malware 1.50.1 http://filehippo.com/download_malwarebytes_anti_malware/
always update so you have the latest signatures before you scan
click on the remove selected button to quarantine anything found
post the scan log here
