can nod 32 dectect keyloggers that can be purchased

i was looking at monitoring software on the internet and i came across this site
awarenesstech.com
the program is called web watcher
my question is, can nod 32 detect these sorts of programs or is it unable to detect what is going on, just as it says in their sales pitch,that no anti virus or firewall program can detect it, and if it can't what can?

 

Yes... it does. I've experienced it with a program called "Real Spy Monitor".
