I was just doing a casual scan when this popped up ...
I never even used this program before (it came preinstalled with my computer) ... and now it shows up as Swizzor variant?
C:\Program Files\Electronic Arts\The Sims Life Stories\Support\SimsLSLauncher.bin Gen:Variant.Swizzor.1 Infected (ignored, user did not have the proper access rights)
Please find the file here for analysis: http://www.sendspace.com/file/yy661k
Let me know what you find.
