Thank you Berny. You were correct. I got it going after a couple more attempts. The first few times it kept getting interrupted and stopping - I have no idea why. It just seemed very finicky.
But I tried again and it worked and went through the end - took all of 26 minutes
I have a couple of questions -
Where does this scan (launched from the command line) pick up its settings from? It seems to be running with some default values at the moment. For example, How do I enable "iSwift"?
Which files does the Rootkit Scan look at? All the objects loaded in memory? I do see that most of the files picked were Windows System, Common and Font files + Program Files that were open and running
Does a Quick Scan look at all of the same objects that the Rootkit Scan does?
Thank you
