Hi,
Just transfer the file viz. SymMSS.CAB on to the Palm and then double click the file.
It will automatically gets install. Be sure you have 6 mb free space before installation.
Also note to update the virus definition via GPRS as soon as the software gets install.
Further, the SAV for Windows Mobile doesn't get manage with SSC as like Symantec Antivirus 9.x or 10.x
I hope this will help you..
Rgrds,
