Found a guide on PCBugSquad.com on removing this new rogue:
PCTotalDefender is a new rogue anti-spyware program that displays fake information in order to scare you into purchasing the program. This program is typically advertised through sites that pretend to be scanning your computer. In reality they are just advertisements trying to trick you into purchasing the program. It is suggested that you remove this infection as it is known to slow down your computer and display popups for other rogue anti-spyware programs.
