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, reboot each time (if it finds integrity violations)
→ SFC /SCANNOW Command - System File Checker
Run disk check to check a selected hard disk for file system errors and bad sectors on it
→ Disk Check
Do these and report back. We'll do more troubleshooting if needed.
