Good detection rates
In terms of detection of Mac malware by App Store anti-virus apps, Dr. Web Light is second only to VirusBarrier Express. And even then, only barely. Detection of recent malware was at 100%, equivalent to VirusBarrier Express. (This conclusion comes from personally testing against 128 different Mac malware samples in a controlled environment.)
