Finjan has yet to announce how much their product will cost consumers. However, their desktop software costs $59.95 and sales associates at the company expect a similar price for their Palm OS software. Ease of use for Finjan software might also be a concern. Since the software will require users to help define the security policy, users must have a fairly high level of technical expertise or have additional technical support in order to make the software work properly. Finally, Finjan's company reputation is not as substantial as some of its competitors, as demonstrated by a market share of less than one percent in the anti-virus software market.

McAfee Guard Dog for Palm
Similar to Finjan's anti-virus software, McAfee Guard Dog for Palm (at http://www.mcafee.com/wireless/guarddog/guarddog.asp) employs behavioral monitoring to detect viruses that have been introduced to the PDA. Guard Dog for Palm runs constantly in the background to monitor the behavior of installed applications, preventing suspicious activities that haven't been authorized. If a program attempts to make any sort of changes to a PDA that violates a security policy, Guard Dog for Palm alerts the user and asks if it should allow or prevent the action.

Unlike McAfee's Wireless VirusScan, Guard Dog for Palm resides on your PDA. It's an effective anti-virus solution because it protects the PDA against all three methods of virus delivery. Guard Dog for Palm is also a durable solution because it can protect you from future viruses as well as known viruses. This solution only takes up 36K on the PDA and, since it's a behavioral-based solution, the size won't expand as the number of viruses increases.

Guard Dog for Palm has been available since the fourth quarter of 2000 to those who subscribe to McAfee's Wireless Security Center. An annual subscription for the Wireless Security Center costs $29.95. To install Guard Dog for Palm, you need to download the program to a PC and then use HotSync to transfer the program to your PDA. Configuration is merely choosing whether to scan or trust applications that are installed on the PDA. Thus, Guard Dog is very easy to use. As previously stated, McAfee is a highly reputable company and is known for their superior quality products. A summary for Guard Dog for Palm can be found in Table D.
