I had a number of problems with Smart Security. 1. I have NOD32 with the live license on my computer. I have tried Smart Security guessing that it would work 30 days trial. It seems that it tried to use the NOD32 license and stated that the license is expired/non-valid. 2. The interactive mode of firewall worked incorrect. Actually it haven't notified me when my browsers attempted to reach internet and blocked them. Moreover, when I manually created corresponding rules, the firewall still continued to block them. I guess that the 2nd problem may happen due to expired license (1st problem). So the question: How can I try the Smart Security when I have working NOD32. Would deinstallation of NOD32 help (it seems unprobable for me)?
