# Why is antivirus or firewall blocking Talview Secure Browser?

If your Windows or antivirus software flags **Talview Secure Browser (TSB)** or prevents it from downloading or launching, it may be due to your system's security settings.

Rest assured, TSB is a secure application trusted by leading institutions.

To resolve the issue:

* Add TSB to your antivirus or firewall’s list of trusted applications
* Or temporarily disable your antivirus while installing and launching TSB
