Halfway into a million-file scan, it's another two-plus hours to a clean bill of health

You want your Mac security tools to behave like Columbo, or Inspector Plodder from the play Sleuth. Not the fastest of detectives, but one that will not miss a detail. So it goes with the newest VirusBarrier X6 anti-virus and firewall product from Intego. You can set it and go, but you might as well go far away at first. Its initial inspections will take awhile.

On our 2.83 GHz iMac with 4GB of memory, that was more than four hours to do a full scan of our 150 GB of occupied hard disk. Full scan is a choice that the VirusBarrier setup prods you toward once you complete the easy install. Too bad that it’s so easy to send the tool into such thorough paces. VB X6 skips over the “check my malware file for updates” stop, so you notice that your file is “35 days out of date” amid a lengthy scan. We’d lead a user into NetUpdate, the VB checker for updated files, before starting a scan. This is also an “install and force a restart” program, not among our favorites.

A complete scan can be a once-in-a-great-while event, however. VB X6 has got one-0ff scan options for fresh files, or scan the folder, or whatever you want to drag onto nifty interface. The inspector is thorough enough to try to catch malicious scripts, the latest ploy in penetrating you Mac’s defenses. We were glad to see attention paid to a very long list of intrusion techniques like this. Drive-by attacks come out of scripts. You have to hope the malware file gets freshened up plenty to believe VB gets the job done. There’s good reason to believe it’s about 30 days or so between updates. Read the rest of this entry »

It’s not tough to make a case today for better Mac security than what Apple delivers out of the box. Even though your business systems ship with a first-level firewall, they don’t arrive with any anti-virus software. Apple insists in clever ads that Mac security is not the problem that users find on PCs. That is true, but not because of the Mac’s superior designs. Unix, deep inside the system’s heart, is just as vulnerable as Windows. (Some say even more so; Unix security patches from HP for its business servers are a regular delivery.)

The Mac enjoys an easier time in security because Apple’s product is a less juicy target. Malware and viruses are designed to make money for criminals, and the number of PCs out there running bareback is 10 times the number of Macs. Security by obscurity only works until it doesn’t. It’s just a matter of time, sad to say, before the criminals fan out and try to rob your system of power or privacy or both.

Anti-virus software (AV) is not just the paranoid geek’s tool anymore. The last virus we detected came off a Web page, and we last had data corrupted in 1997. But things have changed since Apple moved to Unix underneath it’s OS. Oh, and there’s that thing called the Internet, plus the Flash videos you may use to gather research (like from the Wall Street Journal’s site, now that they’re owned by Fox.) Flash, and Adobe’s Acrobat PDF files, are a big target for malware today.

You have more than one choice for a commercial AV tool for your systems (that wasn’t the case in ’97). What you buy probably should provide both firewall and virus protection. Two leading companies offer very different value propositions in their AV software. MacScan commits to a fixed price, while another supplier uses a subscription fee+purchase price model.
