It’s normal that in the new version of scan report in Scan Options section shown that only 3 options enabled : Memory, File System and Startup although in the options I have enabled all options included rootkits ?
I think you might be misunderstanding what @Alpharius is saying.
I think he is saying that in MB3 if you looked at a scan report it would tell you if you had Rootkit scanning enabled. It would also tell you what other options were enabled and what their settings were. For example for PUP's and PUM's what you wanted to do with them.
I agree. I think the report should tell you this information.
I hope I am correctly interpreting what he was saying.
