Trend Micro reports that "When you visit these websites, a fake Google Chrome error message will prompt you to download an update to fix a supposed security issue. What you’re really downloading is a ZIP file that has an EXE file inside. This EXE file contains a Monero miner that will use your computer’s processing power to mine cryptocurrency for the attackers."

Protection tips include exercising caution when downloading anything from unknown sources (limit software downloads to only trusted websites) and keeping your operating system, software and web browser up-to-date. For Google Chrome users, use the built-in update feature by clicking Help and selecting About Chrome.
