I'm assuming that you've run a malware scan that came up clean. Otherwise, run something like Malwarebytes or Adwcleaner to be sure. These seem to have Microsoft icons associated with them. If they appear in Control Panel/Programs & Features or your Program Files x84, then do a sort by installation date and see if they were installed at the same time as ASP.NET or Visual C++ or some other program. Then you'll know that they are a byproduct of something else. You may simply create a restore point, uninstall and see what happens.
