1. Only open email attachments from people that you know.
2. Only open email attachments when you have been told to expect one.
3. Never click onto a website link contained in an email unless you can completely trust the sender of the message and the web site it is linking to.
4. Never respond to spam email messages – it will lead you to being targeted by other spammers.
5. Never respond to emails that appear to be from your bank requesting passwords.
6. Don't forward junk email, spam or "chain" emails – it wastes time and can make you a target.
7. Be very careful which websites you visit – certain "unsavoury" websites, which you may be prompted to click through to from an email, can download malware without you even knowing it.
8. Never install software from a website unless you are 100% happy you trust the vendor or provider.
9. Always check the website address (called a URL) and make sure it is correct – some hackers will alter the URL of a more respected site very slightly and redirect you to a rogue site.
10. If in doubt – don't! What is the worst that can happen if you don't reply to a suspect email or download an attachment? The consequences if you do can be far more damaging to your business.
