I get questions all the time asking me how to remove a variety of infected files. There are a variety of different things that might be turned up by anti-virus software, some to worry about and many not to. They show up in a variety of places, some of which should not under any circumstances be touched by the user, much less by anti-virus software. How is a person supposed to know how to handle such things, or whether to handle them at all? Read the rest of this entry »

I spend a lot of time telling people about how their Mac protect them from malware. I have even written an entire section on the topic in my Mac Malware Guide. So it may be a bit surprising that I seem to be suddenly turning around and saying the opposite. That’s not the case, though. The Mac still protects you just as I have said… but it’s also important to keep in mind where the holes in those defenses are. Just as a house isn’t secure if the owner is unaware that the back door is unlocked, neither is a Mac safe if the owner isn’t aware of the holes in its security. Read the rest of this entry »

After testing many different anti-virus programs over the last few months, I found something that disturbed me greatly. MacScan, made by SecureMac, is one of only a very few Mac-only anti-malware tools. It has a long history with the Mac, having been around since the very first versions of Mac OS X. Unfortunately, it failed my tests abysmally! The question that came to mind immediately was: why? Read the rest of this entry »

There are almost as many anti-virus programs for the Mac as there are families of malware, and a constant question among Mac users is whether to use one and, if so, which one to use. Last November I began a project to test Mac anti-virus programs to see what malware they are capable of detecting. This document describes the second round of testing, in which I look at a total of 20 different anti-virus programs using somewhat different methods than those used in the first test.

Studies have shown that Windows anti-virus programs do not detect more than 90% of all malware at best. It has been speculated by some that Mac anti-virus software may not suffer the same problem. 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. This document will attempt to answer the question of how accurate Mac anti-virus software is at detecting malware. Read the rest of this entry »
