you are online, you need virus protection. I highly recommend
by Grisoft Corporation. AVG
is offered in both freeware as well as professional versions.
You have absolutely no excuse (other than laziness)
for not protecting your system with AVG.
you are online, you also need a "firewall".
A firewall stands between you and your internet connection,
preventing hackers from spying on or invading your system.
I highly recommend either Zone Alarm or Sygate (click
logo at left). If you don't run one of these utilities
and order things online, you might as well just post your
credit card number for all to see - because a hacker is
seeing it, anyway!!
