Installed avg and now have no sound

I am sick i have paid and installed AVG and now the sound on my computer does not work. Uninstalled eventually and the sound works fine. Re-installed AVG and again the sound stops working. I am sick of this, does anyone have a solution to this problem just wasted £30.00 for a product that stops my computer working to its full potential.
