I not sure what happened to my laptop but I recently found out windows update and window defend was deleted from my registry. This caused me unable to update my laptop and also unable to turn on window defend.
I had already used MalwareByte to detect and quarantine all malware listed. However, I would like to make sure my laptop is free from malware before reinstalling OS. Can anybody teach me how to confirm there are no more malware?
Thank you in advance.
