I attempted to download Spark 2.6.0 for Mac today, and my virus software (ClamXav) promptly informed me that it contained the Trojan horse “Fakesec-310”. I’m deleting the file and will try the download again at a later date - I just wanted to inform you of the problem so that you can fix it ASAP! Please don’t hesitate to contact me if you have any other questions.
It sounds like it is possible we are looking at a false positive warning. If you rescan the file and confirm that it is virus-free, let me know and I’ll be glad to report the issue to the ClamAV folks.
