Virus detection in installing the installation built by InstallShield 2019 Professional

We update our InstallShield projects to InstallShield 2019 Professional.

As we implement the installation built by InstallShield 2019 Professional, in installing procedure, some antivirus software will detect the Trojan threat then blocked or deleted infected files.

Finally, when we try to uninstall the application, we failed to uninstall the application.

By the way, antivirus softwares detect nothing  when we implement the installation built by the former version of InstallShield, and the uninstallation successes.

Do you have any solutions to fix the issue?

Thanks

Re: Virus detection in installing the installation built by InstallShield 2019 Professional

Hi @JerryYeh,  

Nothing to worry about this, basically anti virus software has its own virus definition and algorithm to identify the threats to the system, and these virus definitions /rules are updated almost daily to cope with the latest threats to the system. Usually, anti virus software continuously monitor the system changes and block the suspicious executable if it is not authorized to do those system changes according to the their definitions. Some of the system changes monitored by anti virus software are copying and creating files, spawning new process, network communication, changing system policies, accessing the system registry, downloading files, etc. Installer software does all of these during the course of installation. So, only way to get rid of this to make it authorize or update the respective antivirus software definitions through their reporting channel. 

  • Ensure to sign the Setup installer and its pay loads to prove the identity where it is coming from, and ensure to renew the certificate in every year. 
  • Report the false-positive detection to the respective anti virus Software company, through their reporting channel. While reporting, start with the with widely used anti virus Software companies. Because, mostly others will follow the leaders in this market.

Re: Virus detection in installing the installation built by InstallShield 2019 Professional

Hi

Thanks for your quickly reply.

I always sign the installation with effective digital signature and make sure all the files package by    InstallShield  through the detection  of antivirus software.

And the suggestion item 2 of reply, reporting to wide used antivirus companies is not the solution for the long-term, even if it is the solution,  it should be Flexera reporting to antivirus software to get authorized of InstallShield , right?

In addition, why the setup.exe built by the previous version of InstallShield products won't be detected to  the malware, it seems only happen in InstallShield 2019 series

Hope Flexera InstallShield will fix the malware problem.

Thanks again

Hi, @KiranSreeram 

Flexera seem has a updated version of Instllshield 2019 R3 at the end of 2019 before that they have a hotfix updated at the third or fourth season.

After these updated, the issue was resolved.

The  hotfix of Instllshield seem to fix some certification problems, I didon't record the detail of the hotfix.

Hope the reply help you.

@KiranSreeram @banna_k 

Seems the hotfix doesn't fix the malware issue, the malware problem come one after another.

We use the InstallShield 2019 to create the empty project then build the installation.

Upload the installation to virustotal website, the file of installation will be detected to malware or trojan.

If you install the installation to PC, some generation files of InstallShield will be detected to trojan effected by Windows Defender. Attachments for your reference.

This problem has caused us a lot of distress.

Hope @flexera  will pay attention to this problem and solve it as soon as possible.

Thanks

We found the file that be created by InstallShield 2019 in C:\Program Files (x86)\InstallShield Installation Information\[GUID]\setup.exe will be detected a dangerous Trojan by Windows Defender.

Re: Virus detection in installing the installation built by InstallShield 2019 Professional

Hi All,

 

I have been using Installshield 1019 R3 premier. I faced the same issue where my installer gets deleted automatically by anti-virus.

however once I signed the setup.exe it's all fixed, 

 

but sometimes some antivirus still detects it as virus and I have to manually tell the antivirus to exempt it

Re: Virus detection in installing the installation built by InstallShield 2019 Professional

Hi all

I try to sign DigitalSignature for every file in an InstallShield 2019 empty installation file, but it still be detected the Trojan warning in virustotal.com.

Some antivirus engines don't update any longer, but they still report the warning messages.

Our customers can't understand why our software product can be detected Trojan warning......

 

I have an older version InstallShield, the installatin file build by older version will not have any Trojan warning.
