Hi there and welcome
If you have anti virus installed then it is not needed and actually best not to have it with another anti virus program installed
Go to control panel, uninstall a program, locate it there and you can then uninstall it which will stop the message.
If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
