It is part of the Norton/Comcast security suite.  It prevents keylogging programs from seeing your keystrokes (so as to steal account numbers and passwords and such).  Went through this when updating my parents' computer to Windows 7 ... had to uninstall/reinstall - could not type any number row characters into a browser.
I just reformatted an Inspiron 1300. I do not have much on it right now. I checked in the Control Panel under Programs and see I have the above.  I am not sure how this was installed. I did install Comcast's Constant Guard and their Nortorn Security Suite and a cloud back upservice called Carbonite. I also installed MAM,  and CCleaner When I did a search of Antilogger SDK it appears to be a legimate program. Anyone have an idea where this came from and suggestions on whether I should keep this.
