I am using NSIS installer nowadays a lot than Install Shield. All the time I get these alerts from Mcafee virus guard saying "BehavesLike.Win32.Downloader.tc". I know that the easiest thing to do is use a different AV however it's just every program that uses nsis is now being detected as a threat by mcafee. We have also reported false positive as well. Here is a virustotal analysis https://www.virustotal.com/en/file/...a8af03a8cf186c8c870a86374812d8103a5/analysis/ If there are others who face the same problem please pitch in to mcafee community conversations https://community.mcafee.com/message/355643#355643 https://community.mcafee.com/message/355351#355351
