If this doesn't go away with a full, deep, scan while started in safe mode
(press F8 before the first Windows screen appears) and logged in as
"administrator"--then I would call Microsoft Product Support Services and
get help.
There are a number of questions here--is this real or is it a false
positive? If it is real, you need to hear what they have to say about what
may have been disclosed to an unknown party.
In at least two cases involving keyloggers here, removal of the keylogger
resulted in an inoperable keyboard. So--better to get direct help.
In the United States or Canada, call 1-866-pcsafety.
In other parts of the world, call your local Microsoft subsidiary.
PSS provides free support for issues relating to Virus infection and
security patch related issues. A keylogger definitely qualifies for this
help, but perhaps not all spyware related issues do--I don't know how they
make the determination.
I'd love to hear back how this works out?
