A number of experts agree that the retail AV version of McAfee, Norton and
Trend Micro has become cumbersome and bloated for the average user.
The major criticisms are related to stability and footprint, the most
common problem being slow-downs because of the massive system resources
hogs. There are products on the market with equal or better test results
than Symantec's products, consuming less resources at a lower price (even
free ones).
The retail version of these apps can play havoc with your pc. Uninstall it
using propriety uninstall tools:
Download and run the Norton Removal Tool and try to get a refund:

your computer, please make sure to activate your McAfee subscription before
uninstalling. Reinstalling from a CD or download will only install your
McAfee consumer applications, but may not recover your paid subscription

There are many good free AV applications available, and almost everyone has
his favorite. Most of the users are emotionally attached to their av
application and will have excellent reasons for not recommending any other
brand.
The most important thing here is that all of the available choices listed
here are better in some respects than in others, and which choice is better
for *you* depends on what you do, how you work, and which features you use.
The way you use your PC is different from others.

Do not utilize more than one (1) real-time anti-virus scanning engine!
Disable the e-mail scanning function during installation (Custom
Installation on some AV apps.) as it provides no additional protection.

A-S applications - for non-viral malware.
The effectiveness of an individual A-S scanners can be wide-ranging and
oftentimes a collection of 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, (grab'em all).

"...Windows Defender did excel in behavior-based protection, which detects
changes to key areas of the system without having to know anything about
the actual threat."
A clarification on the terminology: the word "malware" is short for
"malicious software." Most Anti-Virus applications detect many types of
malware such as viruses, worms, trojans, etc.
What AV applications usually don't detect is "non-viral" malware, and the
term "non-viral malware" is normally used to refer to things like spyware
and adware.
Many experts suggest that Windows Live One Care is on the bottom of the
list as far as finding virus\malware\trojan.
