Active Windows System Suite

[Active] Windows System Suite

I was wondering if this protective software called Windows System Suite is actually endorsed, recognized, or authorized by Microsoft? It's through Witabtt LTD. and I believe it is not a true protective software because when I Google searched this company and website I found many listings referring to them as a fraudulent spyware company. Ever heard of them? The actual name of their software is Windows System Suite. They came up on my computer under a different name through a Google search of a totally unrelated topic and claimed to have found about 25 serious viruses on my computer which when I ran a complete scan using AVG protective software, it showed no viruses. However, their notice of virus threats continued to pop up on my screen and there was no way of discontinuing their pop ups. Please help. Thanks.
