it would be useful to include a keylogger detector in the CIS 3.5 ;D
see http://www.snoopfree.com for the best example of this type of software i have found, it doesn’t work on 64bit windows however & has bugs with full screen applications & games.
If you choose to install Defense+, you’ll get keylogger protection (and a lot of other protection again unknown malware).
If you should only wish to have the keylogger protection from Defense+, you can go to the settings and have it monitor only attempts to log keystrokes.
