Well , I installed it yesterday so this review will be short.....program installed OK, I may have had the same problem you had with the download.....First impressions are favourable .... it is both an AV and a firewall application. The program must have the virus signatures updated before using.....Very detailed information regarding what is blocked and allowed by the firewall....Many features and settings to explore........After initial configuration program runs well, however I noticed a definite lag in the time from when a desktop icon is clicked and the time the page opens....this was longer than ZoneAlarm ..... the AV scan is thorough and quite long, but the quick scan is quick....I'll know more about the AV when it blocks something.
