In addition to filtering content, it offers limits on what applications can be used to access the Internet, and blocking of media, newsgroups, peer-to-peer networking, and a number of other network features that may be used to get around content filtering. This program is Intego's enhancement to Apple's parental controls, with a number of additional options, including filtering phrases in chat sessions, such as those that might be used by online predators ("are you alone," "can we meet," and so on). ![]() The firewall warning will also show you where the program is residing on your filesystem so you can quickly access it if needed (useful for tracking down potential malware).ĬontentBarrier has a number of additional options beyond Apple's parental controls. Intego's reverse firewall is a solid implementation that should be able to prevent unwanted program registration and personal information from being sent, in addition to catching malware that attempts to make external connections. Initially all connections will be brought to your attention, but (as is the case with Safari) once you've accepted a connection option then this setting will be saved and you won't have to approve it again in future. However, because many programs these days use network connections (for update checks, registration connections, syncing, Web connectivity for help files, and so on), if you enable a reverse firewall be prepared for a few weeks of warning messages while you fine-tune the firewall to meet your needs. ![]() Reverse firewalls are a great way to lock down the security of your system. When a program tries to contact the Internet, VirusBarrier will warn you and provide options to stop the connection. If you access an online banking site with Safari that uses the secure HTTP protocol on port 443, then VirusBarrier will require you to authorize that connection separately. This is done on a network port basis, so when you launch Safari and try to contact a server (such as VirusBarrier will ask you to allow the connection over the default HTTP port (port 80). VirusBarrier's reverse firewall, categorized as its "antispyware" feature, when enabled will block all outbound activity unless you specifically allow it. Reverse firewalls (of which another popular option is Little Snitch) allow you to monitor outgoing traffic and allow or deny a program access to external servers. Given that most modern-day malware attacks include attempts to steal data and send it to remote locations, the inclusion of a reverse firewall is an added benefit. Unlike most scanners that will watch folders and schedule scans, VirusBarrier has both incoming and outgoing firewall options to help keep the system safe. Sandboxing flaw is no real problem for OS X.DevilRobber Trojan now disguised as PixelMator.OS X and Windows protect you well enough as long as you install the os updates. I mean if you have sensitive data the extra precaution won‘t hurt but for private users virusscanners are not actually needed anymore. Especially on Mac where the main attack pattern is phishing and malicious websites, not exectuable files. Or uninstall.Realtime file-based virusscanners these days are just „feelgood“ tools that are actually more harmful (due to their own security flaws that allow attackers to take them over and get no detection and full root access in the process - and of course causing false alarms, more often than not to keep you in a state of constantly being threatened and getting positive reinforcement that you run a tool that seems to protect you) and won‘t protect you anyway from a well designed 0day exploit attack. And check if you can lower heuristics setting. Report it to Intego so they can whitelist these files. If they all say it‘s fine then it‘ll be fine. You could upload some of the files here to check what other scanners are saying: ![]() Most likely (overly aggressive) heuristics used by your virus scanner.
