My MSE finds and quarinines stuff online without any need to scan and it suits the computer I am posting from.
However, as many folk rate Avast as a better package and MSE clearly isn't removing your virus then I would install Avast (free) instead. If the firm won't let you uninstall MSE then just go to the controls and temporarily untick Real-time protection (under Settings). It is unwise to run more than one AV together in the background.
There are often times when one AV handles a particular virus better than another.
Will your firm let you use MalwareBytes - see #1? This can find and fixes things that AV's cannot and the free version doesn't run unless requested. In my opinion it would be best to try this first because it is good at dealing with these fake AV's.
Always pop back and let us know the outcome - thanks
