Compared to Windows users, Mac users have been relatively unaffected by malware attacks. Cybercrooks, however, are just as aware as antivirus vendors are about Mac vulnerabilities. With the growing number of Mac users, cybercrooks see more potential for malicious activities, especially as Mac users tend to have a false sense of security and not usesecurity software. You only have to read this blog to learn that cybercrooks are adapting Windows malware to target their Mac counterparts.
We should never underestimate Mac security. Avast! Free Antivirus for Mac offers free protection against the latest malware designed to attack Mac operating systems. As all other Avast security products, the Mac version participates in frequent, independent tests. Recently avast! Free Antivirus for Mac was not only certified by AV-TEST but it also received 100% in the latest Mac Security Test & Review conducted by AV-Comparatives in July-August.
We are proud to share the results with you!

By definition, Adware is a program bundle which renders advertisements in order to generate revenue for its author. In a more strict sense, e.g. for security solutions, it means an application/installer whose nature lies somewhere between a potentially unwanted application and proper malware, like Trojans or Spyware. It might use more or less aggressive methods, starting with tricks and ending with fraud, to achieve its goals to benefit its distributor, while staying as innocent as possible on first sight. We blogged about an adware downloader a year ago.
Now we focus on two selected adware examples: The first is a Windows installer called Linkular and the second is a well-known application called Genieo (with a focus on its OS X version.) Being in the wild for a few months, the detection within AV products reached only partial coverage in both cases, with very similar numbers on VirusTotal (~10-20 %, see Sources below). However, the OS X adware Genieo is additionally flagged by OS X-specific security solutions. Considering maliciousness, the Windows adware is far more dangerous and invasive than the OS X one and also more than other Windows Adware examples we usually see. Here’s the comparison:

Compared to Windows, Mac users have been relatively free from malware attacks. But cybercrooks are just as aware as antivirus vendors of the behavior of users and their false sense of security and their habit of browsing the internet without security software.

AVAST aces malware detection test
Over 300 malware samples and 35 applications were used to measure the effectiveness of products built specifically for Mac in a recent SecuritySpread.com test. Multiple machines running different operating systems were used to ensure the reliability of the test, and for real-world results, Macs that are used every day for a range of tasks from web development, media center, movie editing to gaming were included. avast! Free Antivirus for Mac had the highest detection rate among them all. The results can be found here.
The Security Spread test was done with avast! Free Antivirus for Mac 7, but in preparation for the official public release of Mac OS X 10.9, aka Mavericks, avast! Free Antivirus 8.0 has been released. The changes are mostly under the hood, and it requires version 10.6.8 or newer. Download it here.
avast! Free Antivirus for Mac was launched a mere week ago, and it only took three days to reach the #1 position on CNET’s download.com. avast! Free Antivirus for Mac fulfills the need for quality security just as the Mac community is recovering from the high-profile Flashback Trojan that infected 600,000 Macs.
