So any way......
#1 is Zone Alarm.
A firewall, your first line of defense against the Internet.
You can download it here, from PC World,
(a great little computer magazine for us common folk pc users)
#2 is Avast.
Why pay for expensive anti-virus software,
when you can get a great one for FREE!
Download it here, also from PC World.
#3 and #4 is Spybot Search and destroy,
These programs will search and remove those annoying spyware and adware that sneaks a ride into your computer when you click on certain Internet ads or links.
Not really harmful, but tracks your Internet surfing,
And of course, they're FREE!
I've been using free protection for 3 years now,
and I'm bug free!
Just make sure you run the programs regularly.
And that means more than once a year!
