Secure your computer
It is vital that you keep your computer secure - both physically (by keeping your machine securely locked away) and from virus and malware attacks. Attacks like this can destroy your hard work and can also quickly spread to people on your contacts list and infect their machines as well.
In order to prevent this from happening, you first need to install and use a reputable anti-virus program, such as McAfee, which you must keep updated. McAfee is available at no cost to you and can be obtained from our Downloads section. You also need to regularly accept all patches and updates to your software and operating system as soon as they are released by the vendors. Thirdly, you need to ensure your work is always backed up.
