Detecting malware in panic reports
A panic report isn't the right tool to investigate malware.


Many crashes are coming from commercial and not evil conceived pieces of software. Some of them are coming from MacOS X directly.
Crash doesn't mean malware.
Most of the time you can't reproduce these crashes at will.
To hide their tracks, most crapware will change their name as soon as activated.
If the crapware wasn't active at the time of crash, their won't be any usefull information in a crash report.



The right tools to investigate for malware are :


Tools to detect any system abnormal activity:

Activity Monitor

top

netstat

Little Snitch

This command will show any program which might attempt to penetrate your firewall:

tail -f /var/log/appfirewall.log

...
Tools to detect abnormal components of the system:

kextstat

this command searches for all recent setuid bit files:

find / -mtime -7 -perm +04000 -ls

tripwire

clamav, ClamXav

chkrootkit

...




If finally you think something is suspicious within a panic report,
try to investigate it with the above methods on the system alive.
To check which modules should be there use kextstat. Save a copy of its output, check another day, check when you install a software asking you for your admin password, check when you notice an abnormal slow down.
