When installing and using the VXDIAG diagnostic device, it is strongly recommended to temporarily disable your antivirus software or firewall, or add the VXDIAG software to the whitelist.
This advice is not because the VXDIAG software is unsafe, but rather due to the way some security programs react.
Reasons for Disabling Antivirus or Firewall
Lack of Microsoft Digital Signature
VXDIAG’s offline diagnostic software is designed for testing and learning purposes. Since it does not carry a Microsoft digital signature, certain antivirus programs may mistakenly flag it as a “potential threat.” This can lead to blocked installations or deleted files that are essential for the software to run.
Firewall Communication Blocking
Firewalls may interrupt communication between your computer and the VXDIAG device, causing connection errors or failed diagnostic sessions.
Driver and Patch Removal
Some antivirus programs can incorrectly remove or quarantine the necessary drivers or patches required for VXDIAG software to function properly.
Reduced Stability During Diagnostics
If antivirus or firewall software interferes during diagnostic or programming processes, it may reduce system stability and lower the success rate of operations.
Best Practice for Smooth Installation
Before installation or usage: Temporarily disable your antivirus software and firewall.
After installation: Once you have confirmed the device is working properly, you may re-enable your security programs.
If issues persist: Restart your computer, temporarily disable protection again, and reinstall any missing drivers.
Conclusion
Temporarily adjusting your antivirus and firewall settings is a preventive measure to avoid false alarms and ensure smooth installation and operation of VXDIAG software. This adjustment does not compromise your computer’s overall security but instead helps guarantee a stable connection and reliable diagnostics.
