Search Engine Security for Google Chrome?

According to the vendor,

"Most hijacked websites used for Blackhat SEO check the Referer header and the User-Agent, to decide whether to redirect the visitor to a harmless spam page or to a malicious domain (Fake AV page, Blackhole exploit kit, etc.). By modifying these 2 headers when the user leaves a Google, Bing or Yahoo! search, Search Engine Security fools the hijacked site into thinking that the visitor is not a real user and therefore avoids redirection to the malicious content."

Are you serious? We all know it is trivial for the hijacked site to change their codes not to check those two headers. It is not really smart to try to fool bad guys and give good users a false sense of security.
