Ohhhh....Ms. LaFr..... must you be so catty?

Opera is also good. Mozilla/Firefox foundation goes back to DOS 3.0 (perhaps before)

Also use free versions of:
Zone Alarm
AtGuard
AdAware
Spybot

Symantic ON-LINE - free scans (recommend overnight)at least monthly.

Gibson Research Center - http://www.grc.com (to search for leaks) at least go their for the education of how your machine reveals "ALL" to the world.

NEVER click on ANY helpers (even the smile-faces) - use Contl/Alt/Del and close your browser if you get unexpected downloads.

Sincerely,
Gargoyle
