Is Dr.Web LinkChecker safe?

Clean risk

Dr.Web LinkChecker sends selected or clicked URLs to Dr.Web's online reputation checker.

When you use its link-check feature, Dr.Web LinkChecker opens a Dr.Web results page with the selected URL included in the request. For supported social-network link checks, it also sends the clicked URL and site name to Dr.Web's online checker and uses the response to show the link status.

Shared hosts - 5 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
