A free version of Omega Core Audit is available for Windows and Mac systems. It offers protection from online threats like malware, spyware, Trojans, vulnerabilities, and so on. Apart from this, you will also get the support of a free online chat as well as a dedicated helpline number. If you are facing issues with this app, you can contact its toll-free support at 1-866-566-9977. With this in mind, you can check if the app you're using to perform any scan is trustworthy and not some fake one. The software has the ability to perform a pre-boot device scan. If you are not familiar with pre-boot malware, then it's an app that is downloaded and installed on your device without your permission. Once pre-boot malware is found, it will hijack all the critical operating system files such as Operating System Kernel, BIOS, System Configuration Table (sched_param), Windows Registry, Windows Driver, and Drivers folder. In this case, you will have no chance to clean your computer without using a system restore disc. This online application is completely free. Hence, you don't need to pay anything for its use.
