Half a year ago, I've tried to download a specific ".exe" file (from here: http://www.emptyloop.com/unlocker/). It was indicated as a potential threat. Of course, I've found a workaround, and thought that this is some kind of a temporary issue. Today, the same file is still blocked: firefox says "Blocked: May contain a virus or spyware ...", chrome also says "This file is malicious". I still believe that this is a false-positive. VirusTotal shows 2/55 ( https://www.virustotal.com/en/file/b3284358029388637e642077f99e81e81144d8dab2f2623e263dbb5b625be746/analysis/ ). I've looked through * "False positive on docx from facebook" ( https://support.mozilla.org/en-US/questions/1048742 ), * "How does built-in Phishing and Malware Protection work?" ( https://support.mozilla.org/en-US/kb/how-does-phishing-and-malware-protection-work ) * "How to prevent Firefox from blocking my software download if Google Safe Browsing simply doesn't respond to false positive reports in Web Master Tools?" ( https://support.mozilla.org/en-US/questions/1054121 ) And I feel like I understood the basics. The question is - are there any ways to report this false positive, so that it would be fixed? Either firefox-specific, or GoogleSafeBrowsing-wide? Any positive experience, "success-stories"? Currently, I've found the following ideas: * Report via Google webmaster tools - probably won't work, since it's not my site. * Try to contact those 2 of 55 AntiVirus companies, and ask them to fix those signatures - maybe after that it would get removed automatically?
