Follow what they say re removal
reboot and install a couple of the free scanners in the sig link below to ensure clean up.
With Malwarebytes do not install the free trial as it will clash with Mcafee install the free version . There are two places you get this offer in the web page the free version is show beside the trial of the premium version and at the end of teh install you get offerred to convert to teh free premium trial. Do not do this.
Run adwcleaner as well.
The Trojan could have downloaded other malware so you need to do several scans I assume.
