I have a warning that says Defence+ is not functioning properly, however, when I run diagnostics it states that no problems have been found. How do I correct this problem please?
Do you have other security programs running in the background? If so, which ones?
May be left overs of previously installed security programs are in the way. Try using removal tools for those programs. Here is a list of removal tools for common av programs: ESET Knowledgebase . Otherwise do a Google search with terms “removal tool” and * name of product or vendor*.
