Hi Stephanie,My name is***** will try my best to help you with your question.
Did you recently install any Windows updates?
Did they install fully and correctly?
Is this happening on a laptop or a PC?
Have you recently performed any cleanup or similar tasks on the computer that may have inadvertently removed or damaged files?
What antivirus software are you using?
Do you have a malware checker installed?
Do you check regularly for viruses and malware?
What is your level of experience in computers? (e.g. basic, intermediate, advanced)?
