Everything you need to protect your business

Not all antivirus software is created equal. Only Avast Business Antivirus includes thirteen features dedicated to protecting your business from malware, ransomware, and spyware. Take a look.


Actively scans files, URLs, and email attachments to protect your business from malware, spyware, ransomware and more.

File Shield

Automatically scans files that are opened on a PC to make sure they’re malware-free, without slowing users down or getting in their way.

Web Shield

Ensures every website visited is trustworthy by checking the URL and website certificate, before any risky connections are made to your network.

Email Shield

Open every email and download every attachment confidently. We’ll check both incoming and outgoing emails to ensure they’re completely malware-free.

Behavior Shield

Deeply-rooted malware can hide inside your running programs. Behavior Shield monitors them all for any suspicious activity to shut down attacks.


When an unrecognized file is downloaded onto one of your PCs, a copy will be sent to our experts at the Avast Threat Labs to identify if it's safe or not.


Efficiency is key for any business. SmartScan combines antivirus, software update, network security, and performance scans into a single one-click fix.

Wi-Fi Inspector

There are more ways than ever for cybercriminals to sneak onto a network. Find and fix whatever weaknesses might be putting you at risk with our network scanning tool.


You lock your business’ doors — so do the same for your network by employing a powerful, customizable Firewall that stops unwanted visitors in their tracks.
