I have a new computer and have been trying to download my security onto it before I delete it off my old one but keeps saying that there is something wrong with the security certificate I had just renewed my security on my old computer before getting new one /my certificate is for one computer for 12 months

Janet, Also Community 'Search support'… Have a look @ this AVG article (http://avgclick.me/LicenseTransfer).
