It is called ‘Personal Security’ and it produces its own version of Window’s Security Center which looks almost the same as the real thing except that the ‘Shield’ symbol is a mirror of the real one.
The Personal Security control panel looks like this. Needless to say, this control panel will only allow two functions. One will temporarily hide it, and the other will allow you to pay for the full version.
If you attempt to use Internet Explorer to find fixes that will see it off, PS warns you that the site you are visiting is not safe and, if you continue to download anything which might help you, it ‘red screens’ and that is pretty much it.
When I last saw this crap, it was only infecting Internet Explorer. Laughably, it did not see Firefox as a threat. By downloading and running Firefox, it was possible to get access to any and all tools that help get rid of Personal Security once and for all.
I do believe that I have written about it before, but it is doing the rounds again and a reminder is in order. The good guys at Bleeping Computer have done a nice piece on its removal, so I will not bore you with my own account.

Despite the appearance of the PS Security Center, this is NOT a Windows function, and does not come down via Windows Update, so quit blaming Microsoft.
