Posted 5 August, 2006 Ditch Internet Explorer Restricted User profiles We now recommend that Windows
users should surf the Net in Restricted User mode. This means no software can
be installed and system files and settings can't be altered. Microsoft explain
the different
types of user on their website.
It's important to note
that the restriction will affect some software, which is why Microsoft don't
set this up as the default. One account should be setup as an administrator
and password protected. That password should not be obvious to the other users.
You need a Firewall
If you have installed Windows
XP Service Pack 2, you'll find the security centre and firewall much improved.
The firewall is much easier to use than the earlier version and is turned on
automatically. We still recommend installing Sygate and then disabling the Windows
firewall. Patch your System Anti virus Spyware remover The Windows
Defender tool does a good job of keeping the nasties off. This is a free
download but only works on Windows XP and 2000. If you are using other versions
of Windows, then Spysweeper
and Ewido are excellent
tools. Spybot
looks for software that snoops on your web surfing while advertising software
is the target of Adaware.
Using the two together catches most of the unwanted rubbish that can clog up
your browser. We recommend running them once a month. Like virus checkers, they
need to be kept up to date. Browser hijackers Internet filtering You can filter your Internet
connections. The Net Alert website compares
home filtering systems while businesses tend to use corporate firewall system
like the Watchguard Firebox. These systems aren't
infallible and take some setting up.
Supervision Common sense The net is full of shady
places and characters, you need to take care when strolling its dark alleys.
When you are on the net, use some caution, make sure your defences are up and
avoid the more dubious websites. By using common sense and some basic software
you can keep out of most trouble. Happy surfing. Originally

You need a both software and common sense to stay safe while on the Internet.
The Internet is a great resource, but while you surf the net your computer can
collect all sorts of nasties. On the net there are viruses, spyware and all
sorts of traps waiting for the unwary. If you are going to spend time on the
net you need to be prepared.
One of the biggest problems for Windows users is the vulnerabilities in
Internet Explorer. A simple way of avoiding these problems is to simply not
use it. We recommend Firefox as the alternative, it can be downloaded from the
Mozilla homepage.
The reason Windows users are far more prone to security problems than Mac
users is that Windows users run as Administrators. This means the normal
user can change anything on the system. On Apple Macs and other systems, normal
users do not have these privilege.
The most basic protection for your computer is a firewall. A firewall stops
the bad guys from seeing you on the net and allows you to give permission over
what programs can connect to the Internet. Windows XP has a basic
built in firewall, but third party products like Sygate
Personal Firewall and Zone
Alarm offer more protection.
All software has bugs. Most viruses and worms take advantages of those bugs.
Keeping your operating system up to date helps protect you from the obvious
holes. Both Microsoft
and Apple
have sites to help keep you up to date.
Viruses are the biggest scourge of computer user and even experienced users
can be caught by them. There are a lot of programs on the market and most of
them are effective as long as you keep them up to date. The free edition of
AVG is a bit more
basic than the full featured commercial products, but does a good job of basic
protection.
You don't have to be surfing to dubious sites or file swapping to have your
computer clogged with spyware. Even respectable websites can add tracking cookies
and data miners. We recommend using at least two spyware removers, which you
should run every few weeks to keep your system clean.
A favourite trick of the advertisers is to install Browser Helper Objects.
These add toolbars and features to web browsers. Some, like the Google, Norton
Anti-Virus, Bigpond and Acrobat helpers are useful, while most are an annoyance.
BHO
Demon is the best tool for checking these, currently it is not being further
developed, but it can still be downloaded from the bottom of the linked page.
If you genuinely concerned about what the kids see on the computer, we'd recommend
installing the family computers in high visibility places so usage can
be supervised. In businesses, staff should be given an acceptable usage policy
that clearly defines what they can and cannot access on the net. If you suspect
any inappropriate usage, you should talk the individual concerned as soon as
you become aware of it.
Common sense isn't infallible, but it's the best protection. Be careful
about the sites you visit, don't agree to download software you don't understand.
If you don't know what if means don't do it, before agreeing at least do a search
on the net for information wheat you are being asked to download. Do not open
suspicious emails and avoid opening dubious attachments,
even if the email seems to comes from someone you trust,
