The latest AV-Comparatives test results have convinced me to consider buying AntiVir Premium. However, when I follow their "purchase" link, it takes me to THIS site, which... 1- States prices exclusively in EUROs, including VAT. Parts of the site are in German. 2- Asks for a checksum for my credit card -- which I have NO idea what they are talking about. The site offers no explanation. I tried leaving this block blank but it won't accept the entry without it. So I gave up. (Screenshot is below, but with personal data omitted) It seems to me that these folks are not quite ready for prime time. They make it so diffiicult to buy their product that it is VERY off-putting. Does anyone know a link for buying the premium edition where they cater to United States folks?
