Bear in mind that Comet Cursor got caught collecting data without their user's permissions. While the company insists they are only collecting info on cursors and not personal info (and by all reports, that's true), it wasn't exactly nice of the company to do so without notifying users.

I can't say for sure it's Comet Cursor, because I do a thorough cleaning when there's a problem found with a machine, but it does seem to be the common denominator.
