Andrea is having trouble using Google Chrome. She even tried to remove and reinstall it. Leo says one possibility is to try and run Chrome in safe mode. If this works, then there may be an extension that's corrupted or broken and therefore breaking her browser. There could also be a malicious extension. Andrea should also clear her cache.
Andrea should try creating a new user account and logging into it. If there's no issues there, then she'll know the problem is something in her user account. Here is how she can completely uninstall Chrome from her Mac. It's more than just dragging the icon to the trash can. Then she can reinstall it and see if that resolves the issue.
