MS AntiSpyware seems to be the same application as Sunbelt
Software's CounterSpy. Application has many similarities
in appearance, in quirks and in effectiveness (very
good!). Problem is when you install on a PC that had
CounterSpy you MUST uninstall CounterSpy first then delete
c:\Program Files\Sunbelt Software and all of its
subfolders and files.

Quirks: PC must be logged-in (security issue) for
Scheduled Scan to run. If the update utility encounters a
problem, it will hang the PC at the splash screen.

MS did solve another annoyance with CounterSpy: you had to
reinstall CounterSpy under every user's profile. Way to
go, MS!

This is probably because CounterSpy also uses the Gian
Engine. Just my guess

Microsoft purchased Giant Software. Giant licensed it's stuff to
Sunbelt, who packaged it as CounterSpy.
