Forget DSO--it's not real. new.net should be removable via the control
panel, add or remove programs, or, via their web site (yes, this is supposed
to be safe!) Microsoft Antispyware also seems to remove it, but it may take
two passes in safe mode. eGroup isn't something I know one way or another
about. In general, if Microsoft Antispyware identifies something, but
doesn't seem to be able to clean it, trying in safe mode may help, but is
not a panacea. A Tools, suspected spyware report from an infected system is
useful, if that function works on your system.
