From what I read, the Fix Me Stick is supposed to do those removals but it's not cheap ! Most decent anti-virus programs will quarantine those for removal. Here are two free ones that should do the job for you and then leave them installed so it won't happen again.
AVG 2016 | FREE Antivirus & TuneUp for PC, Mac, Android

Malwarebytes | Free Anti-Malware Detection & Removal ...https://www.malwarebytes.org/antimalware
