Personally I think you can do better than Norton for free. Get the free version of Avast.
Download and Save the installer.
Download and save the norton removal tool
Uninstall Symantec (save the product license key in case you decide to reinstall it:http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20080710133834EN&ln=en_US)
Run the Norton Removal tool.
Another possibility is Microsoft's free MSSE:
Still another free anti-virus is Avira:
(Just choose one. Multiple anti-viruses will fight each other.)
I think any of the above is a better choice than Norton (which is a real resource hog).
If you feel you need added protection then the free Online Armor firewall is a good fit. http://www.online-ar...-armor-free.php
In addition you should install filehippo's UpdateChecker:
and download and install any updates it recommends. (don't do the Betas) Make sure you have the latest Java and remove any older versions which may call themselves:
Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, J2RE, J2SE
If you use Firefox then get the AdBlock Plus Add-on. WOT (Web of Trust) is another you might want to try. For the paranoid, No Script is another tho this one can be a pain since you will have to tell it which sites you trust to run scripts.
The equivalent to AdBlock Plus for IE is called Simple Adblock and you should install it too: Adhttp://simple-adblock.com/
If Firefox is slow loading make sure it only has the current Java add-on. Then download and run Speedy Fox.
. It seems to work best if you reboot right after running it. You can run it any time that Firefox seems slow.
Be warned: If you use Limewire, utorrent or any of the other P2P programs you will almost certain be coming back to the Malware Removal forum. If you must use P2P then submit any files you get to http://virustotal.com
before you open them.
If you have a router, log on to it today and change the default password! If using a Wireless router you really should be using encryption on the link. Use the strongest (newest) encryption method that your router and PC wireless adapter support especially if you own a business. See http://www.king5.com...-120637284.html
for why encryption is important. If you don't know how, visit the router maker's website. They all have detailed step by step instructions or a wizard you can download.
