Install a firewall and virus-checking on your computers.
Make sure that your operating system is set up to receive automatic updates.
Protect your computer by downloading the latest patches or security updates, which should cover vulnerabilities.
Only allow your staff access to the information they need to do their job and don’t let them share passwords.
Encrypt any personal information held electronically that would cause damage or distress if it were lost or stolen.
Take regular back-ups of the information on your computer system and keep them in a separate place so that if you lose your computers, you don’t lose the information.
Securely remove all personal information before disposing of old computers (by using technology or destroying the hard disk).
Consider installing an anti-spyware tool. Spyware is the generic name given to programs that are designed to secretly monitor your activities on your computer. Spyware can be unwittingly installed within other file and program downloads, and their use is often malicious. They can capture passwords, banking credentials and credit card details, then relay them back to fraudsters. Anti-spyware helps to monitor and protect your computer from spyware threats, and it is often free to use and update.
