Avast Internet Security


For those that want deeper privacy protection

Tweet to your heart’s content, shop, or bank safely and ‘like’ – well, anything you like. Internet Security’s intelligent threat-detection keeps your identity safe online, and now adds an extra layer of anti-ransomware protection for your most important files and photos.




  • A smarter Smart Scan – We’ve redesigned our Smart Scan to be better than ever, and you can now even schedule it
  • Improved performance – We’ve reduced the amount of disk and CPU usage our antivirus needs during installation
  • Improved stability – We’ve unified some headers across the app for greater stability
  • A cleaner goodbye – If you ever uninstall us (gasp!), we now do a better job of removing all our files
  • Bug stomping – Sensitive Data Shield scans no longer finish prematurely, and Mail Shield no longer blocks connections if it can’t connect to an IPv6 address
