On using the "update" function today in MalwareBytes anti malware software (MBAM),
(please note the update downloaded a new version of MBAM dated 26/03/09)
and spybot was last updated on wed 25/03/09)

teatimer detected and warned of the following process:

27/03/2009 07:52:43 AM Encountered and terminated PerfectKeylogger in C:\Documents and Settings\All Users.WINDOWS\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\mbam-setup.exe!

These two pieces of software have co-existed for over 6 months on my machine with no conflicts till this week. between them killing many nasties.

any idea if this is real? or just a false positive?
