Be sure to back up your data regularly, and make sure your anti-virus software is always up-to-date. Cloud technology has made it very easy to set an automatic backup for your system, so check with your carrier and/or company to make sure that your information is backed up on a regular basis. For those that are not backing up in a cloud, it is recommended to do regular backups onto an external hard drive to save those important documents from being lost forever.
Your anti-virus software should prompt you to install new updates as they come available. The internet moves quickly and is constantly evolving. Good anti-virus software should detect newly developed viruses and provide updates to combat them. Check the settings on your software to ensure that your anti-virus software is providing optimal protection.
