I have to say I've been a fervent supporter of KAV but thought I'd give NOD32 another try because of the slowdown to my system caused by the KAV real-time scanner. NOD, on the other hand, causes minimal slowdown, if any. While I didn't like the GUI of NOD before, it's not so bad on second viewing. I also like the fact you can purchase 1, 2 or 3 year licences. The main reason I liked KAV was due to the fact you could use extended databases which detects a lot of trojans and malware (diallers, pornware etc.). So, if I switch to NOD32 - 1) Will I still be protected against trojans and malware ? 2) What won't I be protected against ? 3) How often are the database updates released ? 4) By default, how often does NOD check for updates ?
