"Rather than processing them as they arrived, Agnitum Outpost Pro Security Suite 2009 initially accepted all the email into the Windows Mail inbox and then scanned them afterwards, which took a long time to complete. Its accuracy was average - it correctly spotted 96 percent of the spam but of the remaining 4 percent 'non-spam', over half of it was still junk. Training definitely helps here.
The improved Agnitum Outpost Pro Security Suite 2009 offers good but not the best of breed security – and as with Avira, the bar for ease-of-use has been raised by the likes of Norton Internet Security 2009. OPSS' lack of smartness and relatively high price makes it an also-ran in the AV stakes."
