After releasing Fidelizer Pro for a few hours, there was a strong demand of disabling security services from Fidelizer Pro users running Extremist optimization level. So here I’m releasing a patch to disable security services manually. Please apply this patch after installing Fidelizer Pro 6.7. You can also disable the following services manually in services.msc

Base Filtering Engine (For Windows Firewall)
Windows Defender (Windows 7 only)
