What is Z-lib?
Our system marks Z-lib.pub as suspicious. The decision is based on a cluster of weak trust signals, not one isolated event.
Examples we frequently observe in this group: ownership data that cannot be verified, support pages with no workable contacts, reused template content, and redirects/scripts that do not match the visible site purpose. Each item alone may be explainable. Together, they increase user risk.

Z-lib.pub is affiliated with the Russian Federation, a nation that initiated a military attack, thus committing a crime against humanity in the form of war against Ukraine for the past 3 years. Our company, Gridinsoft, is based in Ukraine.
