That's good been using it ages now, there is also one called ScriptCryptor for VBS and JS but it isn't free.
The problem of the program is that it obfuscates the code, if you notice, in %temp%, there is your batch fully open. Most surely is a good tool.
Yep, pure false-positive... This application have an random file generator, hide the batch on temp, and delete... Also, I recommend IEXPRESS, I've worked with WinRAR SFX / 7Z SFX Tool, +1 for 7z, having the manifest editable resource
@lysy.lbn... not, sure from your posted picture what type of file you are trying to create package for... is it a .cmd or .bat file? also Drive O:\?....... .RPT file? I would make sure any file I was creating package for was on same Drive as Iexpress .. ie. C:\ .... that's why I create a desktop folder containing the file I want to package.
