I am very happy with the 'smooth' and unobtrusive manner in which NOD32 is protecting my system. Now I want to install NOD32 on my wife's laptop as well. I would prefer first installing the trial version. However, when I installed and later upgraded to the full version via the built in update function, there was a discrepancy with the internet filter version and build numbers. They were older than those in the full version. See this thread... https://www.wilderssecurity.com/showthread.php?t=158525 Is this still the case ? If so I will just have to uninstall the trial version before installing the paid full version, as I did on my desktop. Another question please: When viewing the logs after a full scan, one would expect the blue locked items to be always the same, unless there are more restore points or something new was installed that has protected files. However, some scans show locked ...Crypto\RSA\MachineKeys and at other times these are absent from the full scan logs. Regards and thanks.
