Since i have installed avast i have performance issues, the programs won’t start as smoothly as they did before installing your Avast Internet Security garbage and i can´t update W10 which falls in loop telling me that it will rollback the update everytime it tries to update. I am very annoyed with your horrible product and i want my money back.
Perform a clean installation of Windows 10.
Before doing so make sure there are drivers for all the hardware you have.
Keep in mind that there are several bugs in Windows 10 that Microsoft still hasn’t solved.
did you remove any preinstalled or previous used AV before installing avast?
