First, I know nothing about Total AV, and can't comment on how good it is.
But most important, you should *never* have more than one one anti-virus running at once. They can conflict with each other and cause problems. They can also slow down your computer.
One remaining point: As far as I'm concerned, McAfee is a poor choice of anti-virus programs these days. You would be better off dumping both it and Total AV, and using the built-in Windows Defender.
