Multiple AutoApps Schedule virus scan with Tasker

Hello everybody, I have this project I tried to make but it did not really work like I wanted to, so here I am asking you, the experts (spoiler alert: I am a noob in using autoapps and tasker).
I have avast antivirus installed on my phone and what I want it to do is a scheduled scan every night. I know that the app has already that feature but I don't want to keep avast active the whole day. I am using greenify to keep it quiet and what I wanted to do is to wake up the app and make the scan run in the background when my phone is locked (almost like what a wakelock does).

I found a way that is to launch the scanning activity of the app using tasker, but the problem is that the activity cannot run when my phone is locked (as soon as I unlock it, the scan starts).
I could potentially make a task that wakes up my phone, unlocks it, opens the apps, makes the scan run and then hibernate avast app and relocks the phone, but that is not what I want to do. I want everything to be in the background and at a predetermined time during the night.

I tried to look into app services and intents, but as I said I am a noob and everything I know is that you can start a service or call an intent with tasker. What I miss now is to make something in practice that works and I really count on the community for help.
