I can delete MS Juan but it keeps coming back.
But you need to boot to Safe Mode, and run at least, a good a/v program
and a good spyware program to remove whatever keeps reapplying that
registry entry.
"Safe Mode with Networking" should allow you to update your compromised
a/v software before the full scan.
And as a last resort, or just as further protection against the next
infection, Spybot S&D includes "Tea Timer" which alerts you to registry
changes. Once you set it to not allow that change, and to remember the
reply, you shouldn't see it added again. Tea Timer can also alert you
to other changes, but it is a nuisance at times.. You can turn off the
alerts at each remembered block or allow operation though.
