Am getting a red security icon in task bar of Vista first time today after no such problems for the last few weeks after purchase. Right after purchase I went through all the steps: download from registered users page, paste login and passwd (in email) into fields during install, etc. Automatic daily updates seem to be working correctly, however, after pasting and sending NOD32 information page to ESET, noticed that it says "Trial Version" with 19 days left. Thus, I am trying to understand why "Trial version" is showing in the information, even though I downloaded, installed and pasted login & passwd in text boxes during install? Also, why is Vista security center not seeing NOD32?
