Every time a new Windows virus hits the news (and the PCs), Mac users smugly go about their business and crow about how thereis [
Sic--Ed.] "hardly any" viruses for the Mac as opposed to the "thousands" of Windows-based viruses...but are often at a loss to pinpoint the exact evidence to support their claims. Supposedly, "everyone knows" that Macs have fewer viruses, but just how few has always been a bit of a mystery. In light of this, I decided to run a quick check on the exact numbers involved.
My source? Network Associates (NA), sellers of the McAfee and Virex antivirus products, and one of the leading names in computer virus/anti-virus/security software alongside Symantec and the oft-quoted Sophos PLC.
I kept my search fairly simple--this is just idle curiosity, not a paid research project, after all--but as logical as I could:
1. I went to NAis Virus Information Library
2. According to this site, "More than 71,000 virus threats exist today. The McAfee AVERT Virus Information Library has detailed information on where viruses come from, how they infect your system, and how to remove them."
OK, fair enough. Iim [
Sic--Ed.] not going to look up all 71,000, but thatis [
Sic--Ed.] pretty specific...Iill [
Sic--Ed.] take their word for it.
3. Next, I ran an advanced search using simply "Macintosh" as my criteria.
This kicked back a total of 612 virus listings.
4. Next, I subtracted out a couple dozen "Hoaxes"...hoaxes are not viruses, these are exactly what the name implies--phantom "chain-mail" style myths which perpetually circle the globe like the Flying Dutchman or the Wandering Jew, never settling down due to shmoes who keep forwarding them to their family & friends (with the best of intentions and the most annoying of results). Hoaxes are basically unintentional spam mail--annoying but not really dangerous, and thereis so much actual spam out there nowadays that theyive pretty much been buried by it. This brings the total down to 580.
5. I also deleted one which got listed only because the description stated that the virus does NOT affect Macintosh systems...the Boolean search threw it into the mix. Total: 579.
Before we go any further, note that weire already down to less than 1% of the total...even though Macs make up about 5% of the total INSTALLED BASE of computers worldwide (this is how many are IN USE, NOT how many are being sold each quarter/year, which is what "market share" means), depending on your source.
6. This is where things start to get very interesting. You see, out of those 579 total viruses which affect some versions of the Mac operating system, youill [
Sic--Ed.] notice that the vast majority of their names start with a WM/ or XM/. I checked these out, and sure enough, this means that theyire [
Sic--Ed.] a Macro virus which runs exclusively on some versions of--you guessed it--Microsoft Word or Microsoft Excel (there are a few Word/Excel Macro viruses which donit [
Sic--Ed.] have WM/ or XM/ in their names as well). In fact, over 95% of these so-called "Mac" viruses are actually directly made possible by Microsoft software. If you take these out of the equation, which seems reasonable to me since there are solid alternatives on the Mac to Word and Excel, just as there are alternatives to Windows itself, youire [
Sic--Ed.] left with the following number of viruses that affect the Mac and canit [
Sic--Ed.] be blamed on Microsoft in any way, shape or form: 26.
Yes, that’s right: 26 out of a total of over 71,000.
However, Iive [
Sic--Ed.] left out one of the most important factors here: All 26 of these, along with the other 553 Word/Excel Macro viruses, were designed for the OLDER versions of the Mac OS (and the older versions of Word/Excel, to be fair). None of this has anything to do with Mac OS X, which is the relevant system to look at.
If you remove the viruses which donit [
Sic--Ed.] affect OS X, you know what youire [
Sic--Ed.] left with--at least, as of this writing, and to the best of my knowledge?
Zero. None. Zip. Zilch.
Sorry to Make You Cry
