This is a class I teach at the Hernando County Computer Club. It explains strategies that make your computer safe.
We will create a data partition to separate your data from the system. That is an extra protection for your data.
Then we will briefly cover the choices for security suites and virus scanners and I will make some recommendations.
An extra focus on 100% safe surfing with the sandbox will be demonstrated.
As main topic, I will show you how to image the system with free Macrium. You will see the complete imaging cycle from the imaging setup and execution as well as the successful recovery.
Note that the recovery with imaging works in all cases where your system stops working - regardless whether it is due to a system malfunction, a virus or a defunct system disk. It is the ultimate lifeline.
I will also point you to an excellent website that covers up-to-date information on all system security aspects.
The course material (a PDF) can be downloaded from this site.
