Scan when executing
Here you can specify the types of file that should be scanned at the moment they are run or “executed”. It is recommended that all of these boxes are checked.
Checking the boxes “scan programs when executing” and “scan scripts when executing” will ensure that all programs and scripts will be scanned at the moment they are run to ensure they are clean and will not cause any damage to your computer or your data.
If the box “Scan libraries (DLLs) when loading” is checked, all DLL files will be scanned when they are loaded. This may result in some applications starting more slowly, but will significantly increase the security of your system.
