I understand your frustration but no security tool can cover 100% of malware out there, if ZA is configured properly and with good attention from the users your system can be efficiently protected
and your data kept secure without the need of piling up security tools
that often help the infection to get in rather than protecting the system.
I would suggest you read carefully this thread:
xyz was not detected. What I should do? <== Click Here
You should have not spend any money in fixing the PC, by following the steps in this thread:
Malware Clean-up Guidance <== Click Here
or by getting voluntary free support from bleepingcomputer or spywarehammer forum (links in the Guidance) you would had your system fixed. Moreover its not the first time you post here, so you should have seen the malware section here...
TDDS malware is often embedded in fake antiviruses and fake tools, these needs to be installed with the consent of the user. So, more attention on what you install is key to keep your system clean. Also ensure forcefield virtualization is ON in your ZA Extreme to avoid drive-by-download infections.
If your system is used by others ensure they connect with another account with limited user rights and protect ZA with a password to avoid been shutdown or uninstalled.
