Hi guys, been trolling around looking at v3 and v4 posts and am a bit intimidated about upgrading. Seeing some of the horror stories...anything short of a "smooth sailing" upgrade would be overwhelming given what's on my plate right now. And yet, it seems like a good idea. So........... My System: Windows XP SP2 Online Armor (Paid version) SpySweeper v5.x NOD32 v2.7 (I've only two or three times in years gotten a virus warning) FDISR v3.21 Build 205 1. Which Eset AV version is most stable? 2. What are the advantages / downsides of each? 3. Any conflict with the above? 4. I remember years ago using Blackspear's "template" to configure NOD32 which was imperative for me (otherwise clueless). Is there one for versions 3 & 4? 5. My subscription is valid thru 9/11/09. Does one simply upgrade and the ESET system knows I'm registered? 6. Do I uninstall NOD32 first? Or not? Thanks for your guidance all.
