Warning about a potentially harmful site
Sometimes web resources contain not only useful information, but also malicious code. Visiting these sites may infect your computer with viruses, as well as damage or steal your data.
To protect users, Yandex regularly checks indexed sites for malicious code. If malware is detected, a warning is displayed in the snippet of the infected resource: “This site may compromise the security of your computer or mobile device”.
Yandex antivirus and Sophos® products are used to check pages.
We don't remove infected sites from search results, because they may contain unique and useful information that is relevant to your query.
By visiting such sites, you put your computer or mobile device at risk. There's always a chance that you don't catch a virus, because certain conditions are often required for malware to work (such as a particular browser version or specific software installed on your computer). It's also possible that not all of the site pages are infected.
However, you shouldn't ignore warnings of a potential threat. If you still need to visit the site, open its cached copy or take other security measures.
For more information about how malware gets on pages and how to protect your site from infection, see Yandex.Webmaster Help.
