(DO NOT SCAN WITH YOUR ANTIVIRUS AS IT MAY ALREADY HAVE BEEN HEAVILY INFECTED FOR EITHER NOT FINDING INFECTIONS OR INFECTING FILES WHILE SCANNING..)
8. Download Additional Malware/Spyware detection tool such as MalwareBytes Anti-Malware here http://www.malwarebytes.org/ or any other.. and Scan Your System.
9. If possible, Download Antivirus Rescue Disks from Antivirus Vendors such as Avira (Recommended), Kaspersky (Recommended), Norton, AVG etc. and Create a Bootable USB Stick or CD/DVD Disk and Scan your System from Boot... If your system is heavily infected, then thoroughly scan your system and delete any infected files found because those files will only spread infection and cannot be recovered.. (Please Note, this process may render your System Unstable or Even Unbootable.. Follow this Process only if you already have minded up to Install a Fresh OS)
10. If everything else fails, The next Best thing you can do is Install a Fresh Operating System and Follow Step no. 9 above... This ensures you that if you Install Fresh OS, it'll not get Corrupted or Infected just after Installation although it may get infected if Infection is Still Residing on your system. If above step is followed, your system will not be getting Infected until you receive infection from a medium such as USB Drives or files downloaded from Internet...
