Defender Not Compatible with Norton Internet Security 2007



I received the following message when upgrading from Norton Internet Security
2005 to Norton Internet Security 2007: "The programs listed below are
incompatible with this Norton product..." and it listed Windows Defender.
Can anyone share more information about this "incompatibility"? Thanks.

Rick take a look back on the 22nd of Sept. in this newsgroup for this
thread while you're waiting for a possible update to your question:

"Norton Internet Security 2007 wants me to remove Windows Defender"


Rick-I am running Norton Internet Security 2006 and also feel probably not
enough for sypware. Does anyone feel OK to run SpyBot Search and Destroy
with NIS? This only runs when you do a scan.




Norton is a resource hog, it can severely cripple your desktop environment,
doubling and often quadrupling the amount of time for certain applications
to open.
I would suggest you run Norton's removal tool to make sure you have
completely removed this product:

Then get a refund :)

The effectiveness of an individual AV scanners can be wide-ranging and
oftentimes a collection of AV scanners is best.
There isn't one software that cleans and immunizes you against everything.
That's why you need multiple products to do
the job i.e. overlap their coverage - one may catch what another may miss.

Be sure to keep the on-demand av scanner(s) (manually) updated on a daily
and perform a full scan weekly with alternate scanning engines.
