There have been reports of the AZORult trojan being hidden within a map for COVID-19 (which would show it’s spread of confirmed cases globally). ESRI has attempted to put out better information on what is happening between the John Hopkins University map they have on their website and the downladable map that contains the malware.
You can find the explanation about the two maps and how to protect yourself from the malware version on ESRI’s website. Scroll down their page for the visual difference between the online map and downloadable map (which contains the virus).
You can learn more about COVID-19 on the NH government website, at the CDC website and call 2-1-1 with any questions or concerns about surrounding the illness.
