I though it would be closed or that you took no action, both would require you to run it again. Seeing the areas reported as infected I knew those would be found with the quick scan saving you a couple of hours. That is why I suggested it

First Open the avast chest, right click the avast icon, select Start avast antivirus.
Once the memory scan is done the simple user interface is opened, right click in the middle of it.
Select Virus Chest.
Click the User Files section.
At the top of the window you will see File, click that.
From the drop down list select add.
From the Explorer like pop-up navigate to the location of the C:\Users\Nicola\AppData\Local\Temp\CmdLineExt02.dll file.
Highlight (select) the file and click Open (this doesn't actually run or open the file) but will copy the file to the chest.
Ignore the avast pop-up and Close (button) the window.
You should now see the file copied into the user files section of the chest.
MBAM
You should have your report screen in front of you (scanner tab of MBAM), I'm trying to do this in the dark as I have only ever had to do it once before. All of the detected, infected items will be listed (and the box to the left ticked).
When you right click on one of the entries you should get a list of options, Quarantine, etc. that is by far the best option, select that.
That should hopefully get rid of those items.
