Community-sourced early warning system

AVAST Software designed CommunityIQ as a community-based service to provide our Avast Virus Lab analysts with data taken from the actual web-browsing experiences of Avast software users. As over 80% of new malware infections now spread via the internet, and the global Avast user community provides us samples of new viruses as they encounter them, CommunityIQ thus provides us with the best, most up-to-date signature-based detection available.

How it works

Avast CommunityIQ is an early warning technology that is sourced – both voluntarily and anonymously – by our customers. Data acquired by Avast CommunityIQ is used to update our databases of viruses and infected websites, and for other statistical purposes, and can include (for example): URLs of visited websites or information/files that AVAST Software identifies as potentially infected and information on the nature of those identified threats (e.g., viruses, Trojans, tracking cookies, and any other forms of malware); URLs of several sites visited before the infection was identified; information about the sender (not including personal information), the subject of emails identified as potentially infected, and information on the nature of those identified threats.

1. On 8 April 2014, Microsoft stops support for Internet Explorer browsers running on Windows XP. This will put your computer and data, such as credit card and online banking details, at greater risk to hackers and malware.

2. Several browser alternatives exist, but we at Avast use and recommend Chrome, as we find it to be the most-secure option available.
