I doubt that there are no new threats. Marianna always posts new variants of spyware programs. You can also find some new spyware or its variants at http://vil.mcafee.com/recent.asp the new threats (Program - not virus, not trojan but spywares or adwares).
Mail Wiper and their "Marketing" techniques seems new. Many users reported in Spywareinfo forum of seeing Spy Wiper as Spyware and Hijacker - http://forums.spywareinfo.com/?showforum=11

I haven't check SpywareBlaster, Ad-aware or Spybot - S&D detection list to find out if we are protected from this Spy Wiper or Mail Wiper threats.
