To me it looks like the problem or a similar thing sort page. This Web page is not properly ranked by some antivirus companies, I think. Not only a site and is not only an antivirus and internet security software. There are a number of events such as the example. The problem is not actually about avg but Wix web developer or administrator about the site. They are not authorized or your own Web site, security companies, so it blocked the avg originally explained.
