As a big fan of Universal Extractor who has been just updating the bin directory with the latest Inno, upx and 7zip files, I decided to download the latest version 22.214.171.124 from the link in the first post. Before installing, I extracted the setup file with my old version of U.E and uploaded the main Uniextract.exe v v126.96.36.199 file to Virustotal. It had a malware/trojan score of 8/46: https://www.virustotal.com/en/file/4ed07940b2420274f1afc95780b7343f32a6d301740aebf326d000f7888e460e/analysis/1383832739/ Baidu-International Packed.Win32.Autoit.H Commtouch W32/GenBl.83A3B1CA!Olympus Comodo UnclassifiedMalware ESET-NOD32 Win32/Packed.Autoit.H Kingsoft Win32.Troj.Generic.a.(kcloud) Symantec WS.Reputation.1 TrendMicro-HouseCall TROJ_GEN.F47V1026 VBA32 Trojan.Autoit.F Jotti's analysis had 3 positives: http://virusscan.jotti.org/en/scanresult/4b7a5a9516bf88f0a97237821a938e27a79737c4 I also zipped the bin folder which contains all the unpackers and scanned that. That had a score of 6/47: https://www.virustotal.com/en/file/7c675a19f8bafe272bfacc09c13f123971c75cbf870e4e0aaca4835a220bd5be/analysis/1383836325/ I don't have the time to upload the files one by one. These could always be false positives, but I'm surprised it hasn't already been discussed in this thread. I would like to use an updated version of U.E., but these positives are troublesome.
