To remove malicious code from the server, follow our instructions.

Undesirable programs

The last check showed that the site has files or links to files that have had extra software added. This could happen either at the desire of the site's owners, or without their knowledge, as the result of hacking.

The extra software may include suspicious programs that are capable of harming the computer, disrupting other software, or changing settings.

Currently, the site is shown in the search results with the warning “Be careful when downloading files from this site”. Links to files (or the files themselves) containing undesirable software should be removed from the site. If they are not detected during the next scan, the warning will be removed from the search results.

Behavior analysis

The Yandex antivirus robot analyzes the behavior of JavaScript code and other active elements when scanning pages.

If active elements behave according to the heuristic rules characteristic for the drive-by-download attacks, or if the check finds that page attempts to exploit vulnerabilities to execute malicious code, the page is considered dangerous for the users.
