Request for help with infection detection

I keep having Avast popping up with messages such as the one in attached screenshot

As per your instructions I enclose the logs from MWB and Farbar

and the aswMBR log here

Can you guys give me some advice as nothing I can see shows up?

Have you recently installed Windows or performed a repair or something ?

I have recently done both a full system repair and a system recovery - I keep having problems with a file that seems to be lurking everywhere in my system but nothing gets rid of - it’s called swing girls.exe (and no its not anything xxx related) after my japanese wife tried to download a japanese film of that name, I enclose my most recent mwb quarantine scrnshot
