Hello,
How can I remove AVG 8.5, ever since I installed it my pc is slow and sluggish.I have used all usual ways to remove the AVG resulting with a message uninstallation failed.
AVG has a dedicated uninstall program which you need to use. (Look under AVG Free.) If AVG causes your machine to be sluggish then I am afraid that most other security utilities will as well and I do not recommend that you use your PC without one.
