I was wondering what kind of experience (if any) you have of antivirus programs for Pocket PCs. I recently ordered Dell Axims for my business, and I want to ensure that someone doesn't bring an infected file into the network. They all came with a 30-day trial of McAfee, but I've had bad experiences with McAfee in the past, and would rather find a different package. A few I am currently looking at are:

Airscanner Mobile Antivirus 2.0 (Free/Pro)
F-Secure Anti-Virus for Pocket PC
Symantec AntiVirus for Handhelds - Corporate Edition

Does anyone have experiences with these or are there any other ones you can recommend? I'm looking to get one by the end of next week, so any assistance you can offer is greatly appreciated.
