How to stop
spam emails
Report them. Most email
The internet has
become a huge part
of most of our lives.
Some use it for online
banking or shopping.
Others rely on email or
social network tools,
such as Facebook, to
keep in touch with
friends and relatives.
But there are
numerous threats to your
computer and personal
information out there,
with criminals ready to
use the internet to steal
your identification,
financial details, or ruin
your PC by infiltrating it
with viruses or malware.
This guide explains
simply but thoroughly the
steps you can take to
guard against such
problems. It deals with
everything from spotting
scam emails to safer
online shopping and
installing computer
security systems.

programs, such as Gmail and
Outlook, intercept the
majority of spam messages
and send them to a folder
called Junk or Spam. But if
one slips through to your
inbox, report it as spam so
your email provider knows to
filter messages from this
sender in future. You can
usually do this by selecting
the message in your inbox
and clicking Report as junk,
spam or similar.

Avoiding email scams
Con artists use clever emails to trick people out of money.
Here’s what to watch out for and what to do if you spot one
Criminals are turning to
online communication in
an attempt to steal
people’s money or gain
access to their sensitive,
personal information.
Email scams – fraudulent
messages that are carefully
designed to fool you – are on
the rise. So if you’ve ever
received an unexpected
email claiming that you’ve
won a substantial amount of
cash in a competition you
didn’t take part in, or an odd
message from your bank
requesting that you update
your financial details, then
it’s likely you’ve been the
target of what is known
as ‘phishing’.
These realistic-looking
messages do their best to
try to convince you to
hand over your
important details
– such as
account and
credit card
numbers and
passwords – to
criminals who
sell them or use
them to commit
fraud themselves.
The most common phishing scams
How to catch a phishing email
Fake bank account
Phishing scams appear convincing, but
knowing the traits they share can help you
spot them and avoid identity theft more easily.
Here’s what to look out for:
This is an email that claims to be from your bank, building
society, credit card provider or other financial organisation,
requesting that you verify your personal information. It usually
carries a warning that your account will be suspended if you
don’t take immediate action. Typically, the email contains
a link to a fake website run by criminals that looks like the real
thing, where you’re asked to enter your account details.
Banks and other financial companies never send emails
directly requesting sensitive account details, so delete these
emails and never click on the links they contain.
Lottery or competition prize
An email arrives congratulating you on winning a large sum of
money in a contest that you can’t recall entering. The scammer
asks for useful personal information and may request money
for an ‘administration fee’ before the prize is released to you.
Fake survey fraud
This seems an innocent email, simply asking you to visit
a website in order to complete a survey. However, clicking on a
link may result in spyware being installed on your
computer to steal sensitive information.
Advance fee or bank-transfer fraud
There are several variants of this scam, but
most involve a sender claiming to need your
help to move money or other valuables from
one country to another. In return, you’re
promised a significant reward. But first you
need to make a payment or provide your bank
details to further the transaction. Once given, your
account may be emptied.
 The sender’s email address is different from the
organisation they claim to represent.
 The email uses a generic greeting such as ‘Dear
customer’ instead of your name.
 A linked website may look genuine but the
web address in the browser’s address bar may
be slightly different – this can indicate a
fake website.
 Scare tactics are used to get you to act quickly
without thinking – for example, a warning that
your account will be closed unless you verify
the details.
 A request for personal information, such as your
username, password or bank account details.
Never, ever reply sending these details.
 Report phishing emails to ActionFraud, a
government agency that investigates such cases.

Your credit report is a record of your credit history, including
payments and debts, used to approve your application for
a mortgage, credit card, loan or other forms of credit. It may also
reveal suspicious credit activity, if you suspect you’ve been
a victim of fraud.

Keep safe from
viruses and malware
Malicious software, designed to damage your PC
and steal your data, is growing more sophisticated.
Our handy guide will help keep your computer safe
Using the internet with an unprotected computer is like
leaving your front door wide open. Lurking online on some
websites and hidden within some online advertisements,
games, downloaded files and emails are malicious software
programs (malware) that install themselves on your computer.
Programmed by criminals, malware is designed to infiltrate
your PC and cause damage, steal personal information or
delete files. These are the most common types of malware:
A virus is a malicious program that infects your
computer resulting in it slowing down, losing
data or becoming corrupted. Infection
typically happens through downloading files
from the internet, opening email attachments
or sharing USB drives.
With scareware, criminals send you a message
saying falsely that your computer has
a virus and suggesting you fix it by installing a
program (containing malware) or call
a phone number to have it repaired for a fee.

Trojan is software that hides inside a seemingly

Worms are one of the most damaging types of
malware, designed to bring your computer
system to its knees.
Spyware is software that downloads to your
computer without your knowledge. It can
monitor your activity, collect sensitive
personal information about you
and even hijack your browser.

Tech-support phone scams
Be wary if you receive a cold call from
a company claiming that you have a virus,
which they then offer to remove if you allow
remote access to your PC. These callers are
con artists, often claiming to be connected to
firms such as Microsoft. They’re simply trying
to gain control of your computer to steal
banking and other sensitive information or,
again, will pretend to remove the nonexistent virus and charge you for it.
Signs that your computer has become infected
with malware may include it taking a long
time to start up; working unusually slowly;
frequent program or system restarts;
programs behaving in odd ways, or files
being corrupted and unable to be opened.

Action to take
The good news is that you
can help to protect against
viruses and malware
by installing the following
types of software on
your computer:
 Anti-virus software protects
against viruses, Trojans and
worms by scanning for and
removing infected files.
 Anti-spyware scans your
computer and removes any
spyware it finds.

Safe online shopping
Enjoy internet shopping while staying secure
with our top tips for online purchasing
Delivery times
It can be frustrating when
goods you’ve ordered online
fail to turn up on time.
Under the Consumer
Contracts Regulations, items
purchased online must be
delivered within the period
agreed with the seller. If this
wasn’t specified, the goods
must be delivered without
undue delay and no later than
30 days from the day
purchased, or you can
refuse to accept them,
get a refund or sometimes
claim compensation.
The online store is
responsible for the condition
of the goods until you, or
someone nominated by
you, such as a neighbour,
receives them.
Faulty goods
You should place orders only on websites that offer secure payment
card transactions, so your details can’t be read by anyone else. Signs
of a secure site include:
eb address The address in your address bar should begin
https:// rather than the standard http://. The ‘s’ stands for ‘secure’.
reen address bar All or part of the browser address bar may
turn green.
 P adlock symbol Appears next to the address bar or web-browser
frame. Clicking the symbol should reveal a digital certificate that
confirms that the website is what it says it is.
These signs may not appear
on the website until you’re
ready to place your order –
look for them when you click
the Checkout button.
If goods are faulty, not fit for
purpose or not as described
– or even if you don’t like
them – you have the right to
return them and get a full
refund or have them replaced.
When returning faulty goods,
you shouldn’t have to pay
return postage.
 Make sure your firewall is switched on and
Shopping online is quick and
simple, and you can grab
some great bargains. But it’s
best to shop through
a reputable website, such as a
high-street shop’s online
store, and avoid buying from
a site you don’t know, unless
recommended by someone you
trust who has used it before.
Always look for a website
that lists its full contact
details – a postal address and
landline number. Be wary of
shops that have just an email
address or mobile number.
A good online store spells
out its delivery details and
returns policy. It should have
a privacy statement saying
how it protects your personal
information and payment
card details from misuse.
Saga’s website

details, terms
and conditions

statement. We

 Choose a hard-to-guess password when
registering on a shopping site. Make it at least
eight characters long. Avoid names or birth
dates. Try a memorable 'passphrase', such as
'this is my car' and mix letters with keyboard
symbols: '[email protected]'. Use a different password
for each online account, if you can.
 Read the small print so you know exactly
what you’re buying. Check items are in stock
before you buy – reputable online stores
detail stock availability.
 Trust your instincts. If a bargain seems too
good to be true, it probably is.
 Use a credit card for online shopping. If
goods cost more than £100, your credit card
company is equally responsible if anything
goes wrong. PayPal is also secure.
 Sign up for the Verified by Visa or
MasterCard Secure Code service. You
register a password with your card company,
which you enter when buying from an online
retailer who has signed up for the scheme.
 When you’ve finished shopping in an online
store, be sure to log out so anyone using the
computer after you won’t be able to use your
personal information.

Secure home
Your home wireless network can be exposed
to misuse unless you keep it secure
Most people use a Wi-Fi
network to connect their
digital devices around the
home. When connected to
your broadband, it also
allows your computer and
other devices to use the
internet. This gateway can be
a weak point if you don’t take
precautions against people
accessing it from outside
your home to piggyback your
broadband connection.
To run a home Wi-Fi
network and internet
connection, you need
a wireless router. Your
broadband supplier usually
provides one. This small
communications box
connects all your devices and
gives access to the internet.
Most wireless routers have
security already applied –
though check the settings to
ensure your home network is
secure. Newer routers with
the WPA2 security system
offer greater protection, so
consider upgrading to one.
 Change the default
password on your router.
It can be easy to guess,
allowing unauthorised
people access to your
network. Instead, access
the router’s control panel
following the instructions in
the manual and, under
Settings or Security,
change the password to
something stronger.
 Change your router name.
Open your router’s
web-based control panel on
your computer, then under
Settings or similar, change
the name from the internet
service provider’s default.
This means potential hackers
can’t see what brand of
router you’re using, making
it harder to access.
 Create a guest password.
Some routers let you create
a second guest password.
This is useful when friends
are over, as you can give
them this password to
access the internet on their
smartphone, while
preventing them from
accessing any of your
devices on the network.
Protect your PC at home
Keeping your router secure is only half the
story. As well as ensuring you’ve up-to-date
security software installed on your PC, there
are several Mac and Windows settings you
should check to keep your computer safe.

Browser safety tips
Social networking
Web browsers include safe web-browsing features and
private surfing modes. Always use the latest version
of a browser that your operating system will support.
Your browser will alert you when a new version is available –
updating is free. Most browsers let you fine-tune your security
settings such as browser history, cookies and AutoComplete.
Facebook, Twitter, Google+, YouTube,
Pinterest, LinkedIn and other social networks
let you connect and share with others. Most
sites let you create a profile about yourself,
your interests, hobbies, likes and dislikes. You
can then send public and private messages
to others, share photos and videos, play
games and join like-minded groups, among
other things.
Social networking sites have, however,
become a magnet for those looking to harvest
personal information or scam people.
It’s easy to disclose valuable details on a social
networking site, so stay safe by taking a few
sensible precautions.
