These advanced automated options are only available in the Pro version.
What is your OS ?
What was the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?
The everytime comment concerns me, especially if it is the same filename and location. If you get so frequent infections to consider this option, would lead me to suggest you review your system security. Once your system is clean you should be rarely inconvenienced by on-demand scans catching something on a scan.
You are also probably doing a throught scan with archives to warrant doing it at night ?
Archive (zip, etc.) files are by their nature are inert, you need to extract the files and then you have to run them to be a threat. Long before that happens avast’s Standard Shield should have scanned them and before an executable is run that is scanned. Thorough is also by its design very thorough and perhaps a little overkill for routine use, were a Standard scan without archives should be adequate.
I have only ever done a through scan with archives once shortly after installation just to ensure a clean start state, but with XP for example avast will do a boot-time scan after installation if you select it, this I believe will be quicker and reasonably effective. Like everything in life things are a compromise.
