Hi Den. You're not actually dealing with malware when you get a brand new sys. You're dealing with crapware. Extra suites you don't need etc. Look at CCleaner, I think its called, use to be called crapcleaner... These types of programs show everything that is booting up and installed allegedly and gives you the choice to remove them. Some of them are free and don't make choices for you. Try Bleepingcomputer.com, who's been a pretty good site for some time to research for legit crapware removers.
Malwarebytes is a great free malware proggy still.
