This may be a controversial post, but I'm looking for other users experiences with running NOD32 as 'lean' as possible. For me NOD32 actually already has minimal impact on performance (much less than other AV software I have tried) but I do inevitably notice a tiny bit of lag occasionally. Whatever your view on that, and bearing in mind that I'm a 'cautious user' (I don't download software from 'potentially dodgy websites'), I'd like to have a go at 'tweaking' NOD32 - after all, it does provide the facilities to do so! This is one of the things that appeal to me about NOD32 in fact, and although I reckon I could 'have a go' by thinking things through logically, I'd like to 'pick other people's brains' on this first. Basically the only 'musts' for me are: Http scanning Windows Explorer context menu scanning The thing I'm questioning is - as I run a fairly 'tight ship' anyway, do I really need real-time scanning on program execution, network scanning (I have a NAS device), opening and closing documents, and machine shutdown. I run regular 'full' manual scans anyway and have two CD / DVD drives (no floppy disk). Many Thanks in advance!
