Over the years since we have
started writing newsletters, there has been a much heightened alert
about viruses and spyware. Whilst these are the most likely problems
that may affect your computer as they cause havoc and destruction to
your files. However there is a deadlier form of these out there, they
are the virus warnings and hoaxes, usually sent via email forwarded from
reputable people or organisations requesting they are forwarded to
"everyone you know". Similar hoaxes also exist for competitions you may
have won or other offers that seem to be good to be true.
Unfortunately, there are many
warnings and hoaxes that circulate on the internet on a regular basis.
They usually arrive forwarded in an email from someone you know and you
consequently end up trusting this information and it can difficult to
assess whether the information is correct or a hoax.
Organisations such as AusCERT
(Australian Computer Emergency Response Team) is the national leading
advisor in the Asia/Pacific region provide information freely available
to anyone who subscribes, and the best source of valid information on
such threats. However, they do not suggest forwarding of their emails
and they provide valid references to prove the statements in their
bulletins.
In addition, companies who
produce internet security products such as Symantec and McAfee provide
advise and updates via their respective websites.
Both companies also provide lists
of legitimate threats and risks (including hoaxes). If you receive what
appears to be a virus warning, hoax or not, or a promotion that sounds
too good to be true, visit the following websites:
Symantec:

McAfee:

For several years, CyberGuru has
been advising those who forward such warnings and hoaxes onto us to
confirm via these websites whether these hoaxes are true. We can verify
that the many virus notices we have received have all been hoaxes. When
we receive these, we provide a link to our website listing the current
threats, tools and advisories, sourced from the Symantec website, which
is available at our Security and Virus Warnings page at
http://www.cyberguru.com.au/helpdesk_securityandviruswarnings.htm.
We also provide the forwarded information on where to find out more
about the hoax itself and should your receive any similar messages where
to find out about them as well.
Typically, CyberGuru does not send
virus warnings as these websites provide more up-to-date information we
have access to. However, if we do discover that an actual virus requires
such a warning, we will make every effort to provide this information to
you on the Security and Virus Warnings page. We may send you an email to
advise you to check the website, confirming we are the source of the
information and provide valid references on where further information
can be found and invite you to contact us if you require further
assistance.
Our advice is that if you receive
a virus warning, disregard and delete it straight away without opening
it or any attachments. Do not forward it as this continues it. Even if
the sender forwards it on in good faith, it is likely to be a hoax. They
are constantly sent purposely trying to frightening or misleading users
(often with instructions to perform actions on your computer including
deleting system files) and then requesting you send it on and the loop
goes on. If you are unsure about what to do please call us.
It is timely to remind you to
ensure that you have an up-to-date internet security product installed
on your computer. Should you receive such a virus, then your product
will pick up and remove any virus discovered.
