is Comodo Cleaning Essentials real 100% portable/stealth?

Hi

i 'm comodo lover , i love the firewall

and the Comodo Cleaning Essentials is one of the best or maybe the best anti trojan

the company declares it’s Designed as a portable application , but my question is

is really portable/stealth?
stealth

"stealth" means when an application is launched, used and terminated properly, it does not leave behind any entries in the registry or filesystem

i’m asking because i run Jv16PT and i monitor it , and i found restry keys and file

thanks
cheers
