# Bitdefender Antivirus Update Not Starting? 👉 1-866-490-0338(USA/UK) ☎️
.. Quick Answer: How Do I Force Bitdefender Antivirus Update? 👉 1-866-490-0338(USA/UK) ☎️
To force Bitdefender antivirus update on Windows, right-click the Bitdefender icon in the system tray and select **Update Now**, then wait until the update reaches 100%. If Bitdefender asks for a restart, restart your computer. Bitdefender’s official Windows update guide lists this as the manual update method. ([Bitdefender][7])

.. Bitdefender Says Outdated, but Automatic Update Is Not Moving? 👉 1-866-490-0338(USA/UK) ☎️
You open Bitdefender and notice the update status is old, stuck, failed, or waiting. Maybe the app says it needs updates, but nothing changes. Maybe your internet works fine, yet Bitdefender refuses to refresh. This is the moment when you need a forced manual update instead of waiting for the automatic cycle.
Bitdefender normally updates automatically, but manual update is useful when automatic updates are delayed, the device was offline, the system just restarted, or you want to confirm the latest protection before scanning. On Mac, Bitdefender says automatic update is enabled by default and the app checks for software updates every hour when connected to the internet and Bitdefender Shield is enabled. ([Bitdefender][8])
This guide explains **Bitdefender how to force antivirus update** on Windows and Mac, plus what to do if the update fails or gets stuck.

* Bitdefender subscription is active

* No other antivirus is interfering

* You are using the official Bitdefender app
**Important:** Do not download update files from unofficial websites. Use Bitdefender’s app update option or official Bitdefender offline update page.
