Noob here. Did a boot-time scan.

It came back with 25 infected files. I ignored all (0) so I can have the logs, but not mess with anything. I don’t know where to start. Thank you for your help.

first clear your temp folders with this

then follow instructions here https://forum.avast.com/index.php?topic=53253.0
attach Malwarebytes and Farbar Recovery Scan Tool logs

Ok I did everything up to Farbar Recovery Scan Tool. Here are my logs. Thank you again!

Nothing evident there, they are all in the temp folders so I shall clear those
