I should preface these questions by saying that I am not technologically
oriented and am looking for basic, solid protection.
1. Anti-Virus:
A. What anti-virus do you most recommend and why?
B. I do have anti-virus screened through my ISP, does that make a
difference?
2. Firewalls:
A. If I have a firewall at the router, do I need one installed in the
computer as well? If so, what do you recommend?
B. I'm using W98 right now, but the new system will (obviously) be either
XP or Vista (probably the former). I understand newer versions of Windows
have a built-in firewall - does this apply to both Vista and XP and do I
still need a 3rd firewall on top of that one and the one at the router?
3. Do you recommend a separate program for spyware and if so, which? (I
understand some of the anti-virus programs are now incorporating spyware)
My ISP offers a version of Norton Internet Security. I think NIS is a good
choice if you're not "technologically oriented" because it does a pretty
good job of managing the system without a lot of user input. Some people
hate the Norton product line, but they do work well most of the time and
provide pretty good security in my experience.
Both XP and Vista come with built-in firewalls and they will be ON by
default. The OS firewall will only be turned OFF if you install another
firewall to take it's place. In the control panel there is an icon called
Security Center. When you get the new system open the Security Center to
see the status of the FW, AV & AS software on the PC.
No matter how good the antivirus is I would definitely install a separate
antispyware program with a real-time shield (which means it's watching the
data-stream all the time to intercept bugs just like the antivirus).
Security "suites" usually include all three types of defense (FW, AV, & AS)
so if you go with a suite you only have to make one choice. Another
advantage with suites is the various functions are integrated and you can
see the status on one screen. Norton makes it easy by putting a big green
check on the screen if everything is fine or a big red X if something needs
attention - simple and effective.
Regardless of the software you choose it's important to keep it updated and
let it scan the system on a regular basis (weekly is good). A common
problem is people install decent security software and then let their
subscriptions lapse so the software stops updating - then the viruses start
taking over.
