Cygwin Flagged as Malicious

Trying to get set up per this page, but Virus Total flagged the linked Cygwin install file as malicious. Only one security vendor flagged it, so I’m hoping it’s just a false positive, but on the How to scan software with Virus Total page it recommends reporting any software linked to on this site if it gets flagged, so here I am!

P.S. Thank you for recommending for everyone to scan software for malware – I didn’t realize it was so easy, and have bookmarked Virus Total for future use!

Howdy and welcome to PhotoStructure, @ParkeRanger !

Unfortunately these one-off “detections” are uncomfortably commonplace. It’s a judgement call that you have to make to determine if it’s a “false positive.”

If you downloaded from Cygwin Installation then you should be fine, but you can also verify that the SHAs match:

(VirusTotal will tell you the hash values in their UI: and remember that with SHA validation, all the characters in the hash need to match!)
