Internet typosquatters are registering misspelled domains of anti-virus vendors and making money by redirecting surfers with Google's AdSense pay-per-click program.

The startling discovery was made by Finnish security vendor F-Secure Corp., a company that's being targeted in the elaborate scam.

In a notice posted online, director of anti-virus research at F-Secure Mikko Hypponen said unknown typosquatters operating out of Panama have registered more than 150 domain names with slight-almost unnoticeable-variations of the target URL.

For example, instead of the legitimate www.f-secure.com, the domains "www-f-secure.com" and "wwwf-secure.com" have been registered and set up to point to "nortpnantivirus.com," which is a misspelling of Symantec Corp.'s Norton AntiVirus.
