As title, when using the trial version of NAV 2010 why can't you upgrade to the latest version ?
I'm currently trying out anti-virus programmes (i'm stuck at what one to choose) for Windows 7 Ulitmate x64, and Avira, Gdata and Kaspersky all let you install the latest version when on trial with them, so why not NAV 2010 ?
Unless i'm mistaken about this ?
And if not, how big an improvement does the latest updates make to the performance of NAV2010 such as malware detection, malware scanning speed and system performace etc compared to the 17.0.0.136 version ?
