Motivated by a post on theappleblog.com I installed the rkhunter and wrapper program in order to do a system scan for rootkits. Strangely I got this complete system freeze due to some grep command error (!?) on the first run. To be honest, I actually never had a freeze before if I exclude my experiments with CPU voltages changes.
Some sort of security scanner doesn’t appear to be a bad idea at the end of the day though. Try using clamav as a virus scanner. But, keep in mind that it’s even more proactive to not enter your admin password without thinking and not opening every stupid crap.
