With the DevilRobber Mac Trojan in the news, security anxiety is growing for Mac users. Yes, the current Mac OS includes XProtect, a simple antivirus tool, but malware has been known to disable XProtect updates, rendering it useless.

Mac users looking for a bit more protection can now obtain Kaspersky Virus Scanner ($9.99, list) from the Mac App Store. That's a lifetime license, with no annual renewal required. This tool doesn't have the full malware-fighting power of Kaspersky Anti-Virus for Mac 2011, but it offers useful added protection.

Like the full-scale product, Kaspersky Virus Scanner offers on-demand scanning and daily updates. However, it doesn't get real-time updates from the cloud the way its big brother does, and it doesn't include real-time proactive detection. On the plus side, it uses less system resources.

The low-cost scanner speeds subsequent scans by skipping files known to be safe, just as Kaspersky Anti-Virus 2012 ($59.95 direct for three licenses, 3.5 stars) does. It detects PC and Linux malware as well as Mac malware. Of course the non-Mac threats can't actually run on your Mac, but eliminating them ensures you won't spread them to friends.

Kaspersky Virus Scanner's user interface supports English, French, or German. The product is currently available from the Mac App Store for a one-time price of $9.99.
