The definitions are updated every couple of weeks or so. You must connect to the internet so the new definitions can be downloaded to your computer. The updated definitions detect the latest spy ware--hopefully. In 2 weeks or so, spy hackers make many changes to their spy ware and the updated definitions try to catch these. A version update contains more major changes in the program itself and technically, though I have some ideas am not competent enough to describe these program changes. I suppose you could think of updates as similar to making script changes in Jaws while version updates are equivalent to a new release of the program. -- To post a message to the list, send it to jfw@xxxxxxxxxxxxx To unsubscribe from this mailing list, send a message to jfw-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
