    How do update work with NOD32 or infact any anti virus software. Say for eg when a new definition update has been released is NOD always scanning for updates (in the background) while the PC is on or does the updates server use push technology similar to that of Blackberry so when a new update has been released it will be pushed or forwarded to PC's using NOD32.

    NOD32 checks for updates every 1 hour (by default).

    As far as i know only eScan (eSafe?) and avast! Pro use pushed updates. All others use fixed interval checking.

    Basically push updates provide top reaction times, less or basically no checking overhead (since they're initiated by AV vendor servers) and better bandwidth control (you can limit how many clients can be pushed at once or whatever you like, intervals aren't that flexible except limiting number of active server connections).
    But problem is usually the way how to push them and is often more complicated than simply checking every hour.

    NOD32 is also using "Update on established connection" along with 1 hour check intervals so thats quiet good and more than enough for now.
    It will update as soon as you get online (lots of AVs lack this and it's imo very important) and then every hour.

    I didn't think anyone used "push" technology, unless you're on a LAN with an enterprise management console.

    Most other people are behind firewalls, often NAT routers. How would the venders main antivirus servers keep in touch with each client, so as to "push" an update?

    It is very hard to compare blackberry and antivirus updating IMHO

    When I used McAfee AV v4 they used Push technology, they used something called "Backweb". I believe Backweb is also categorized as spyware.
