Hi As others experienced, NOD32 crashed following the 5418 update. I used the internet for a while afterwards without realising my PC was no longer protected because NOD32 taskbar icon remained green all the time. Eventually I noticed a no protection warning from Windows Action Centre. Fortunately no harm done but I’m now wondering whether I should have Windows Defender or perhaps Prevx running in real-time alongside NOD32. If I turn on Windows Defender, Action Centre warns of performance issues running more than one antispyware in real-time. I’d like to hear some views from the Forum. Thanks.
