Three Days ago, i install Avast Internet Security in my Lenovo G50-80 5th Generation. After 30 minutes, i feel that my laptop is heating up, i ignored it but i noticed that the battery timing of my laptop is reduced suddenly from 5 hour to just 2 hour. i uninstalled Avast, after uninstalling laptop stopped heating up and battery timing comes back to 5 hour.
What is the issue with Avast, there is no other antivirus in my machine, i am using Avast internet licence which i got by referring 21 people, i am using windows 10 64 bit latest build.
