# 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

***

## ✅ Common causes and fixes

| **What Might Be Wrong** | **What You Can Do** |
| :- | :- |
| Real-time protection closes the browser mid-test | Temporarily turn off **real-time protection** only for the duration of the test, and turn it back on after your exam. |
| You’re using both antivirus and a firewall app | Allow TSB in both if you have separate antivirus and firewall tools. |
| Antivirus flags TSB as suspicious | Open your antivirus settings and add **Talview Secure Browser (TSB)** to the list of trusted apps. |
| Firewall is blocking internet access for TSB | Allow TSB through your firewall so it can connect to Talview’s servers. |
| “You may not have the appropriate permissions to access the item” error | Right-click on **TSB icon** and select **“Run as Administrator.”** |

### 🔐 How to disable antivirus & firewall (temporarily)?

> [!NOTE]
>
> **Important:** Only turn off antivirus or firewall protection on a personal device, and only while installing, launching, and taking your exam. Turn it back on as soon as your exam ends. On a work or school device, contact your IT team instead.

* **Windows Defender (default antivirus/firewall):**

1. Open **Windows Security** > **Virus & threat protection**
2. Click **Manage settings** under "Virus & threat protection settings"
3. Toggle off **Real-time protection**
4. Now go to **Firewall & network protection**
5. Select the active network > Toggle off **Microsoft Defender Firewall**

> **Note:** Remember to turn these back on after the test.

* **Third-party antivirus/firewall software:**
  1. Open the antivirus app > Settings > Look for **real-time protection** or **web protection** > Disable them temporarily
  2. Also, check **Firewall settings** within the app and allow **Talview Secure Browser (TSB)**
