What are the downsides to using MacKeeper?
Are any external security programs needed for iMac? I thought Apple engineered security into their programs at their inception.
iMac, Mac OS X (10.7.2)
You really have no need for MacKeeper. It can slow down your computer as well as give a false sense of security. OS X has built-in anti-malware software if you install current updates (such as updating yours to 10.7.5.)

Helpful Links Regarding Virus Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read the FAQ on malware.
For general anti-virus protection I recommend using ClamXav.
