Pretty much so, any security application that hasn’t had development in over a year, really isn’t keeping up with developments.

Any suggestions would be dependant on the circumstances, e.g. if you were still getting symptoms and other general removal tools haven’t resolved it, which doesn’t appear to be the case. But as I mentioned in the quoted text OTS, but that is a specialist tool that requires specialist analysis (essexboy, etc.), so it isn’t a tool that you jump straight in and run without it being requested.
