This is a question (and suggestion): How do I understand the options in 3.0.667 (Vista)? What is confusing is how many areas have the same settings. For example: 1) In the advanced setup, the first item is Antivirus and AntiSpyware. To the right of that is "ThreatSense Engine parameter setup". Once I setup Threatsense there, do those options apply to everything? I'm not sure, because when you go down the list, to email or web for example, I see the option again? Are those over-riding the defaults I put at the top? If so, I suggest a checkmark called "override default settings". 2) Try to find the profiles and how to modify them for a scheduled weekly scan. Once I modify a profile (or create a new one), does it apply for ALL uses of that profile? If so, then when I create a weekly scheduled scan, am I overriding the profile? I think you can see the (what I would call) a DESIGN confusion. I'm never sure what applies and what is over-ridden. Same with targets. Maybe someone can suggest a re-work that will make it clear the hierarchical structure of the settings and how they apply. I've used NOD32 for over a year, and lately I have been trying to change some of the heuristics and other settings to avoid the cpu issues, but I'm never sure if I have to go through everything or not. I don't think a casual user (which I'm not) would ever figure it out. Maybe this thread belongs in the suggested new features, but I also want to understand if anyone can help, how the options and settings work now?
