Although data relating to detection of such antique malware may seem unimportant, it does provide some historical perspective as to the past and present detection rates of anti-virus software. Some malware has little significance, as it is now considered “extinct” and thus poses no danger at all. The next worst after that was considerably higher, at 51%.) The average detection rate was about 65%, or 69% if the MacScan outlier is omitted. (The 4% from MacScan was an outlier, however. That data includes a detailed list of all malware used for testing and a complete breakdown of which specific malware was detected and missed by each anti-virus program.ĭetection rates varied widely, from 90% down to 4%.

The raw data can be downloaded as either a Numbers spreadsheet or a PDF file. The full list of anti-virus software that was tested was:
Enterprise and server products were not examined.

All anti-virus programs were required to be compatible with the latest version of Mac OS X, and the focus was on software that might be downloaded by the average home or small business user. Finally, the anti-virus software was uninstalled and the malware folder (which may have been “tampered with” by the anti-virus software) deleted.ġ6 different anti-virus programs were tested. The results of each test were tabulated in a Numbers spreadsheet. The results were often impossible to export or analyze in any automated manner, often requiring multiple screenshots to save the information, but the information was saved however it could be saved.

(If asked by a setup “wizard,” however, settings to scan for hacking tools or other potentially unwanted applications were enabled.) Then, a fresh folder containing the 51 malware samples was copied onto the same volume as the base system and a manual scan of that folder was initiated. All other settings were left at their default values. Each time, any on-access or background scanning features (if any) were disabled, to prevent interference with controlled testing. All testing was done within a three-day time period, from November 11 to November 13, 2012.Īnti-virus software was downloaded, one at a time, and installed on the base system. All testing was done from a mid-2010 17″ MacBook Pro, while booted from this base system rather than from the internal hard drive. No third-party software was installed on this base system. The resulting base system was also saved to a disk image on another volume, to allow for easy restoration to its original state, should that prove necessary.
Testing was done on a base OS X 10.8.2 system, installed freshly on a 30 GB volume on an external hard drive and updated fully. It is important to note that every malware sample used for testing either was already in the VirusTotal database or has been added to it during testing, and is therefore easily accessible to security companies that choose to look for it. Although it was important to have a large enough sampling to achieve a fair test, some effort was made to ensure that biases were not introduced.

MethodsĪ selection of 51 different malware samples for Mac OS X was collected, representing 19 different malware programs, from a variety of sources. This document will attempt to answer the question of how accurate Mac anti-virus software is at detecting malware. There are hundreds of thousands or millions of different malware programs for Windows, while on the Mac there are only around 33 (by my current count), most of which are “extinct” at this point in time. It has been speculated by some that Mac anti-virus software may not suffer the same problem. Studies have shown that Windows anti-virus programs do not detect more than 90% of all malware at best.
