CIS - Antivirus failed?

[Guest]

Hello,
I use latest version of CIS 3.5. My last scan(scheduled scan) showed me 3 infections - TrojWare.Win32.Hacktool.Prockill. I thought that its false detection. But my SpywareTerminator detected next problem Backdoor.Generic 122602. Its something wrong. 
Why CIS Antivirus hasnt alert at the moment when TrojWare was installed to the PC?
I think...firewall isnt problem because I used CFP 3 with Avast 4.8 since January and I hasnt problem with spyware or viruses.
How can I do make my computer safety?
Thank you for answer

After install Avast 4.8 (without CAV) detected next 6 viruses 2x Win32 Trojan-gen, Win32 adware gen (ad. software), Win32 LdPinch-Eu and Eicar - test file.

No computer security software can offer 100% protection.

If you used CIS 3.5, was it updated (I mean virus database)
Was Defense + ON?
I think when malware tried to install, Defense + should be warned you.

Are you sure that malware did not exist after you installed Comodo?
