Hello,

I am trying to install AVG Security but I get a error message saying AVG Antivirus is already installed, please uninstall the previous version first.

I have already uninstalled all AVG products on my MacBook, so I'm not sure why I keep getting this error message when I try to reinstall?

Thanks,
Fahmida 

Thanks Lathika.

But it looks like you have sent me details for a Windows PC, when I have a Apple MacBook?
