If you look at the list of “executable” extensions posted at the start of this thread, you’ll see that (exe,com,cmd,dll,bin) is not enough.

As for making the GUI richer just to “impress” the user - I really don’t think that’s the case. An ordinary user would rather get confused, instead of impressed. But it’s simply the options that the Stardard Shield offers.
Page 1: here you configure what gets scanned when executed, i.e. when you start it as a program.
Page 2: here you configure what gets scanned when you open a (existing) file (open in the meaning “prepare to read or write”) - for example, when loaded into Notepad. You can also configure the scanning of newly created or modified files (unlike the “scan files on open”, this means that the file will be scanned after it is written to and closed).
Page 3: here you can configure what (suspicios) operations you want to be blocked - there is no scanning for viruses here, it’s just blocking selected operations, no matter if the file is infected or not!
Page 4: here you can set exceptions (what files or folders should not be scanned at all) and some additional options (e.g. silent mode).

Do you really think any of the 4 pages are redundant?

If you have any error logs, could you please send them?
