1. MSE gets 100% depending on the month. Some of the paid ones get 90% depending on the firm and the month. Anything 90% and above is perfectly acceptable. 2. All Security software have special tools. That's all Malicious Software Removal Tool is. An extra tool for special strains. 3. Boot distros will clean your system better then you think you can personally unless you work for one of the security companies or write the nasty yourself you don't have the experience they do. All day every day and even they screw up the clean up. This is why Malwarebytes is such a legend for cleaning up after a infection. If someone gets infected thats not savvy, best thing you can do is clean it up via distro, back up and reinstall. Unless you think you can walk someone through the regestry and .DLLs. Avast has been kicking a lot of ass in the moble market this past year. Ive been watching them for my PC as of late. If MSE doent get a little better on zero day I might switch over this year some time. Dunno yet.
