keylogger.rb and task list metasploit error

[jeffs at speakeasy.net (jeffs)]

Noticed that with the keylogrecorder.rb certain keyboard characters are 
not being recorded.  At least on my system I noticed the backslash "\" 
character does not get recorded.

Also noticed that with kapersky running on my test box a "ps" in the 
session does not show avp.exe

Is this normal behavior for most?
