Since Malwarebytes allows not to register the AV in the Windows Security Center it can work alongside other AV's
With this in mind it will be interesting to be able to have this settings in the interface
Choose types of files to scan (one option or the other)
Scan recommended extensions: specify if File Shield should scan all files or only those recommended by Avast
Scan all files: specify if File Shield should scan all files or only those recommended by Avast
Real time modes (multiselection selection Box)
Scan programs when executing: specify whether you want File Shield to scan programs, scripts, or libraries each time they are run
Scan files when opening: specify which file types you want File Shield to scan each time the files are opened
Scan file when writing: specify the file types you want File Shield to scan while the files are being created or modified
I know it will compromise security but since you can have another full AV workin MBAM can become a lightweight companion. Of course default settings should be like they are now but having this options availble for users open more use cases and business oportunities.
