When I try to download Winrar 5.01 32bit from the official homepage, my Avast (7.0.1474) detects a Win32:evo-gen in my user account temp directory. The file name is Zr+HosKF.exe.part. The file comes immediately when I press the download link. I don't like unknown executables in my temp dir, so I block it, and the download fails. Anyone know about this?
