Hello to all. I have a problem with certain encapsulated applications and Avira Antivirus, I have installed in my PC the free version of Avira Antivirus, and when I run by example “WinZip 12” encapsulated with ThinApp 4.0.1.2866 Avira Antivirus says that there exists the trojan TR/Unpacked.Gen inside the folders that the application generates. The same happen with another apps, by example “Advanced Archive Password Recovery 4.50”, “Maplesoft Maple 11”, “Microsoft Student con Encarta Premium 2009 (Spanish version)”, and some others apps, and this not happen with other software, by example “OpenOffice.org 3.0.0”,” Mozilla Firefox 3.0.5”,” PSP Video Converter v3.30”, … etc (maybe because they are free , jajaja).
Of course, I scan my windows installations in search for viruses (Inside the virtual machine I have installed Windows XP SP3 build 5512 32 bits and my host windows installation is Windows Vista Ultimate SP1 version 6.0.6001 64 bits, both installations in Spanish language) with Avira Antivirus and AVG Free antivirus and they don’t found anything.
Maybe this is a bug in Avira Antivirus because if I ignore Avira Antivirus warnings and search with AVG Free antivirus inside the folders that the application creates AVG don’t found any viruses.
To be more specific: When I run an encapsulated “Winzip 12” and I try to create a ZIP file Avira Antivirus found the trojan TR/Unpacked.Gen inside the folder “Stubs” and the infected file is “verclsid.exe”. The same happen (the same folder and the same file) with “Advanced Archive Password Recovery 4.50” when I open a ZIP file. With “Maplesoft Maple 11” when I run the program Avira Antivirus found the same trojan TR/Unpacked.Gen inside the folder “Stubs” but the infected file is “mserver.exe”. With “Microsoft Student con Encarta Premium 2009 (Spanish version)” the same trojan TR/Unpacked.Gen is found by Avira Antivirus in the EXEs created by ThinApp 4.0.1. 2866, the files “Learning Essentials para estudiantes.exe” (Learning Essentials for students.exe in English) and “Matemáticas de Microsoft.exe” (Math of/from Microsoft.exe) are infected.
I remark again that AVG Free antivirus doesn’t found anything, only Avira Antivirus found the same trojan.
Well, please, someone can install Avira Antivirus in their computer an run any of the Apps that I do mention?????, I want to know if this is a bug or I have to format my machine :(.
And yes, I scan for viruses every installation package and I install Avira Antivirus inside of the virtual machine to check that the installed program is free of viruses (and yes, Avira Antivirus doesn’t found anything).
Ahhh, almost I forgot it: I’m using VMware Workstation 6.5.1 build-126130.
Sorry by my English it’s fatal
