Upgrading from Basic to Advanced (or Premium)

[jastirm 0]

How do I go about upgrading ESET?  I'm not upgrading to the newest version, but rather upgrading from Basic to Advanced.  I have already purchased the Advanced Edition, but am at a loss on the correct procedures to follow, since the online instructions seem to be just for upgrading to newest versions of ESET...

There are basically 3 Windows products for home users to pick from:
ESET NOD32 Antivirus (without Antispam, Parental Control, Anti-Theft and most importantly Network and botnet protection)
ESET Internet Security
ESET Smart Security Premium (includes also Disk Encryption and Password Manager)

If you have v11 installed, you can simply change the product by going to Help and support -> Change product. In case you don't have ESET installed yet, download the appropriate product from ESET's download page.
