Basic computer security

You must run quality security software on your computers to protect your work and private data from viruses, spyware, and other security threats. When it comes to security, there is no substitute for quality. See below our recommended quality solutions. If any of the following is difficult for you, get an IT Expert to do it for you. You must do the following or risk all of your work/data being compromised /think of it as locking your front door/:

Get good anti virus software e.g. one of the below.
Recommended antivirus software:
AVG
Avira
Norton Anti virus
McAffee Anti Virus
Panda Security
Sophos Anti Virus

Be sure to regularly update your ‘virus definitions’ e.g. once per week. Keep your Firewall runing. Install an anti-spyware application. There are many available, some good, some bad. Email Attachments: BEWARE OF ATTACHMENTS. Do not open email attachments you are not expecting. Viruses come with some very nasty messages to trick you into opening the attachement e.g. “Your email account has been cancelled, see attachment for details”. Even worse, the virus looks like it comes from an email address you recognise e.g. from admin@yourDomain.com / where ‘your domain’ is the domain name that you usually use /. Virus attachments can have the following ‘file extension’: .exe, .pif. If you receive a .zip attachment and open it – make sure it doesn’t contain a file with one of those extensions. Do not open attachments you haven’t requested, even if they appear to be from people you know.

 Why do I receive, notices that emails from me could not be delivered?

How did someone else send an email that looked like it was from me?

Why do such emails seem to be from someone who is not in my organisation?

This is usually caused by a virus on someone elses computer sending the emails, but making it look like the emails are from you, or to put it another way: A virus that spoofs the ‘from address’. The important (and annoying) thing to note is that the virus is probably not on your computer, it is on someone elses. So even if you have quality anti-virus software that keeps your computer clean, there is someone else out there who’s computer is infected and sending these emails out.
Make sure you have good anti-virus software and tell everyone you know to do the same.
