Hello;
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

It is considered imprudent to have two fully installed
anti virus applications installed at the same time.
--
Do not run more than one real-time anti-virus scanning engine!
Ensure that the automatic update facility is engaged only for
the real-time scanning engine. Also, if you decide downloading one
of the above av applications disable the e-mail scanning function
during installation as it provides no additional protection.
In fact, most of experts believe that scanning incoming and outgoing
mail causes e-mail file corruption.

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
basis)
and perform a full scan weekly with alternate scanning engines.
