Welcome to my world.
Not on my personal PC's, but at work we have over a dozen servers getting attacked every day.
For a personal PC, if the time stamps seem to show it has stopped, I'd just keep an eye on it and keep updating Malwarebytes and scanning every couple days for a while until comfortable.
FreeCommander may help to find recently changed files (by date). That's the most basic tool I can think of to make sure files aren't getting changed still.

FWIW it could have happened during a given 'session' online, maybe only while a certain ad displayed, .. don't really have to do anything wrong these days to have this type of issue. But if it hasn't stopped I'd be more concerned.

/Our servers battle hack attempts every day 24/7 .. it gets SO old
