Computer Security Tips
We recommend that you run high 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 for our recommended tips. If any of the following is difficult for you, get an IT Expert to do it for you.Consider doing the following or so your work/data is not compromised (think of it as locking your front door):
- Install reputable anti-virus software: Be sure to regularly update your 'virus definitions' e.g. once per week )
- Install a firewall and malware applications: Firewalls will help monitor incoming and outgoing network traffic. Malware programs will help detect and remove unwanted spyware/malware. Many anti-virus packages include both a firewall and anti-malware. If not, consider purchasing a product from a reputable source. Each component provides an additional layer of security.
- 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 attachment 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 recognize e.g. from [email protected] (where 'your domain' is the domain name that you 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 - when I didn't send the email? 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 organization?
This is usually caused by a virus on someone else's 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 else's. 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.
