Why Install Free Avast Antivirus on Windows?

Its installation is quick. Furthermore, it works on most recent versions of Windows.
Check Your PC's Compatibility
Before installing free Avast antivirus on Windows, check a few essential points.

To find out your Windows version:
- Click on the Start menu.
- Type "System Information".
- Check the line "Version".
Internet Connection
You need a stable internet connection. Indeed, the installation file downloads components during installation.
Uninstall Another Antivirus
If you are already using another antivirus, uninstall it before installing Avast. Two active antivirus programs can create conflicts. This slows down the computer and reduces protection.
Go to:
- Settings
- Apps
- Apps & features
Select the old antivirus and click "Uninstall."
Then restart your computer.

Ensure that automatic updates are enabled, so you benefit from the latest virus definitions.

An antivirus protects your system. However, your online behavior remains essential.
