Me I'm in the FP camp (have said as much on the topic above) as that also turned up in my scan, yet there is not a single other trace/piece of evidence of a Dealio associated cr**ware on my system, toolbar, files, registry keys, etc. just this:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\Stats\{E312764E-7706-43F1-8DAB-FCDD2B1E416D} (PUP.Dealio)
I don't use IE and hate toolbars with a vengeance and always on the lookout for this kind of cr**ware.
