computer running slower than it use to?
you may have spyware running on your computer ---there are hundreds of spyware programs out there ---here is a free one ---it is not the one I use I paid for one ---but it is better than not having one
Free Spyware Scanner identifies surreptitiously installed applications. Using updatable ref lists similar to antivirus DAT files, Free Spyware Scanner scours your system, including the registry and temporary Internet files, and looks for traces of recognized adware modules. When it's finished searching, it displays a list of what it found.

A little late to the discussion, but.....
Just joined the forums, and thought I might add a bit for anyone reading this. To start off, I'm a network engineer for a national ISP, and deal with a network node that has almost 20,000 end users.
AVG is great, and so is Avast! antivirus. They are free for personal use, and smaller than norton or macafee, so they impact your computer less.
As far as anti spyware programs go, I lean towards "spybot search & destroy", and "Ad Aware SE". Both are available in free or trial versions, and when used in conjunction, they catch almost all of the nasty stuff out there. microsoft defener is also a great free add-on.
If anyone has any PC or networking questions (platform independant), feel free to email me. I try to check this account every few days.
Just adding my 2 cents worth.
I've been using Norton for years, without any problems. The system I bought last July came with Norton Internet Security, which has a firewall as well as the AV, and it also helps with adware/spyware. I'm not too sure of the effectiveness of the firewall, although it has stopped some applications from accessing the internet all on their own.
I always recommend Spybot and AdAware to anyone who asks for my help with their computers. I've been using them for years as well, and I've been quite pleased. I'm not a high-risk surfer but every once in a while they'll find something. Just make sure you update them at least once a week. I Have Norton run a scan once a week automatically, and I run manual scans on Spybot and AdAware once a week as well. Spybot also has some nice administrative tools which can help with start-up programs and some registry problems. If your comfortable with computers, switch it to advanced mode. No extra charge!
Something else to look at is http://www.grc.com/default.htm. They have numerous small programs which you can dowload for added security. They also have an online test called ShieldsUP! which tests your defenses against hackers. I've used it without any problem.
