I have a new netbook laptop Windows 8. It came preinstalled with Norton but I uninstalled it (using Norton uninstall program) and installed AVG. Both when Norton was running and now with AVG when I have downloaded malwarebytes and I try to update on my modem it won't update, nor will AVG and internet is blocked (effectively I think the internet is blocked), When I uninstall everything works again. I have tried using the malwarebytes removal tool to make sure no residual malwarebytes is left and the same happens again. I ran tdsskiller and it reported nothing. My AVG so far has reported nothing. I am not hundred percent sure but when I was on a cafe weblink malwarebytes updated and the internet ran with malwarebytes; I assumed it was working again. The internet worked up to the pont I ran the malwarebytes update as an effort to run the program. I have removed it again in order to email you. PS I do not have an in-depth knowledge of computing and everything I have tried comes from Google! Please can you help?
