Spybot does catch stuff sometimes, but its known to corrupt the system down as well.
Suggest you to uninstall it.
I and many members on our forum recommend Microsoft security essentials with
a great combination of Malware Bytes.
→ Microsoft Security Essentials - Free Antivirus for Windows
→ Malwarebytes - The Free version
→ Good and Free system security combination.
Run a full scan with both (separately) once downloaded, installed and updated.
In addition, Run this tool and delete anything it finds:
→ Anti-rootkit utility TDSSKiller
Run the system file checker to repair any corrupted files
→ SFC /SCANNOW Command - System File Checker
Then run disk check for hard disk for file system errors and bad sectors on it
→ Disk Check
Keep us posted of the results
