I would add Windows Defender, SUPERAntiSpyware free version, and CCleaner.
I would dump also Norton and use a free antivirus in its place. Of the free antivirus programs,AVG is probably the best.
Roadrunner offers a free security suite.
http://content.rr.com/rdrun/feat_security.htm
FREE Internet Security Suite software to all
Road Runner customers powered by CA. You get
FREE Anti-Spyware, Anti-Virus, Firewall protection,
Anti-Spam, Pop-Up Blockers, product upgrades and updates, and web support**.
---------------------------------------------------
The CA suite is poor but combined with
Windows Defender (free full time spyware protection)
Ad-Aware SE Personal
Spybot Search & Destroy
SpywareBlaster
SUPERAntiSpyware free version
CCleaner
will work fine. I use this on my computer with the windows firewall (part of AT&T security suite). Not the best but it is free, works and is very light on system resources.
AVG is superior to CA virus, but you still need full time anti-spyware protection. AVG has free anti-spyware protection but it is not full time protection.
If you download questionable programs or do file sharing no system will completely protect your computer from yourself and your computer will eventually be infected.
-------------------------------------------------------------------------
All: Install Windows Defender (full time spyware protection)
Perform a full scan.

Install the following five programs and run weekly or at least monthly. You need all five. They are not a substitute for full time spyware and virus protection.
Install and run now.

Note if a scan detects a problem but is unable to remove, start the computer in safe mode with the internet line disconnected and run a full scan.

Additional run this time and as needed.
