[bug] WinRAR and Avast (Win32:Trojan-gen. {Other})
« on: August 06, 2006, 01:59:47 AM »
This is the story: when I download some game or program that doesn't have install routines, I tend to make me one with WinRAR, as it can be customised. What I do is make SFX with some options and custom icon, and here lies the problem. If I used only 32x32, 8bit icon, no problem, exe file is created with that icon, and I can extract it. If I use multiple icon source (you know, ICO file with various size icons in there), I get the error.
I recall there was a problem with Total Commander not showing these icons (and files inside archive) because of unpacking header larger than 128k.

I'm sending it to

Avast v4.7.844
VPS 04.08.2006. v0631-3

WinRAR is the free one v3.51. No skins.

Do you know the name and path of the file that is being reported as Win32:Trojan-gen. {Other} infected?

Yeah, it's the archive I've created... d:\tmp1\avast_problem\problem.exe  ;)
Another archive, no_problem.exe is exactly the same, with same compression method used, only different icon.

If you wish, I can upload it to rapidshare so you can test it yourself. The same archive and icons I sent to avast team. It's a freeware game - no warez.
