Firstly I would suggest you do not use your e Mail address here - create a user name. Secondly it would be helpful if you stated the Operating System and which security programme you are concerned with. Many here can recommend free ones when your one runs out.

You need one anti virus and a couple at most of anti malware, but please state what your programme is.
