The company is pretty new, and that "article" seems to be just some advertisement.. I don't see the need to pay a monthly fee for home use virus protection because of the free available tools like Microsoft Security Essentials/Windows Defender, Malwarebytes Free, etc. It all depends on what fits your likes and browsing habits though. Even with paid software, I would choose one of the Top 20 solutions out there that are well reviewed and tested - ScanGuard is nowhere to be found on those lists. See av-comparatives.org for example.
