IPUMS directs users to download WinGZip or 7zip to decompress files.
When I downloaded WinGzip with the provided link, two malware programs (Segurazo, Goodgame Bigfarm) were installed on my computer which took my IT department three different malware removal programs to resolve.
The IPUMS site is exposing users to malware and these links should be removed immediately.
Thank you for alerting us to this problem. We have removed the links to WinGZip from all our IPUMS data sites. I sincerely apologize for the trouble the corrupted links put you through, but am pleased to hear that you were able to resolve the issue.
Please send a mailing address to ipums@umn.edu so we can send you a mug as a token of our appreciation for telling us about this security risk and mitigating the issue for other users.
