Intego (, a Mac security specialist, has released VirusBarrier Plus, a new Mac antivirus and anti-malware program. Sold exclusively through the Mac App Store, VirusBarrier Plus offers protection from both Mac and Windows malware, as well as other types of malware, malicious scripts, and more.

VirusBarrier Plus is available at a special launch price of US$7.99 for a two-week introductory period. It detects Mac and Windows malware, so Mac users are protected, and so they don’t pass on infected files. It protects against PDF malware, Flash malware, Linux malware, keyloggers, hacker tools, and malicious scripts (PHP, Perl, Javascript, shell scripts and more).

VirusBarrier Plus also lets advanced users run malware scans from the command line, using the Mac OS X Terminal application, to scan all the files on their Macs. It offers frequent, free malware definition updates: new malware definitions are provided at least twice a week, and users can check for updates to malware definitions by clicking a button.
