I am running NOD32 AV v3.0.560.0 (on WXP Pro SP2). ESET is now offering for download v3.0.566.0. In the NOD32 window Update tells me that the virus signature is up to date and provides no facility to update the program. The Advanced Setup, Update is set to Ask before downloading program components. Q1. Why hasn't it offered me an upgrade from 560 to 566? Why do I have to go to the ESET website to find out that 566 exists (with a bit of help from this forum). Q2. How, apart from this forum, do I find out at the ESET website what fixes have been implemented between 560 and 566 (if they are there, I can't find them)? Some forum posters suggest that 566 may fix the slowdown problem. Q3. To upgrade from 560 to 566, can I install 566 over 560; or is it best to uninstall 560 first?
