thank you for all the people who helped me decide whether an antivirus product is still necessary for a pc.
i have made a decision to uninstall the avast antivirus and just use configuredefender and set the protection level to HIGH.
when i clicked the HIGH protection level, it said that it was successful (see picture below)
when i clicked the refresh.. it told me that some settings were not stored properly.(see picture below)
how to fix this?
