I believe it should be fine. But never install 2 or more anti virus software. But I would suggest to invest in Avira internet security or any internet security software. If performance is your concern.
..installing 2 or more anti-virus software to your laptop can reduce the performance of it!..install only 1 anti-virus software..better you use AVG AntiVirus or Avira AntiVirus..i hope it helps!..^_^..
