If you take a quick glance on the feature list, Avast certainly has more features than AVG does in the free variant. However, the Avast add-ones are basically network security; also provided by AVG in a different form. AVG Free Antivirus & Avast both have following in common –
- Anti-spyware, anti-malware and anti-rootkit.
- Web-surfing protection for your web browser.
- Email client protection, if you use one.
- Silent mode for gaming.
And everything else is either AVG or Avast proprietary. AVG has the following –
- Data theft protection
- Data deletion protection
- Remote control of AVG installed devices over AVG Zen UI.
- No registration required.
While Avast offers –
- Home router security for tightened network protection.
- Cleanup of browser plugins.
- A feature that scans for outdated software in a PC to optimize the performance.
- Remote access to other computers for control & file transfer via Avast secured network.
