Last Friday, a blog post by David Felstead, Senior Development Lead at Bing said that the study was flawed because AV-Test used a Bing API to conduct searches instead of using the Bing.com website, which displays warnings about known to be infected or suspicious websites. Bing's API bypasses the warning system and warning labels do not show.
Felstead goes on to say that Bing does block suspicious websites, by disabling the link on the search results. However, why not block them completely? The reason they don't is because sometimes websites get hacked and deliver malware, but get fixed.
|The top result is a suspicious website. When you try to click on the link, you'll see the warning box to the right. If a user still wants to continue, they can still do so.|
|Aside from the search ads, you can see that the malicious result is still at the top of Google's search results, but there is no warning about the danger of visiting the page. This effectively shows that Bing can block malicious websites.|
Yandex, another search engine, is also questioning this study. They question how AV-Test determines a result to be malicious or not, among other things. Search Engine Land wrote a great article about this, so refer to them.
So, what do you think?
