The brand AVG comes from Grisoft’s first product, Anti-Virus Guard, launched in 1992 in the Czech Republic. In 1997, the first AVG licenses were sold in Germany and the UK. AVG was introduced in the US in 1998.
The AVG Free Edition helped raise awareness of the AVG product line. In 2006, the AVG security package grew to include anti-spyware as AVG Technologies acquired ewido Networks, an anti-spyware group. AVG Technologies acquired Exploit Prevention Labs (XPL) in December 2007 and incorporated that company’s LinkScanner safe search and surf technology into the AVG 8.0 security product range released in March 2008. In January 2009, AVG Technologies acquired Sana Security, a developer of identity theft prevention software. This software was incorporated into the AVG security product range in March 2009.
According to AVG Technologies, the company has more than 200 million active users worldwide, including more than 100 million who use their products and services on mobile devices.
On 7 July 2016, Avast announced an agreement to acquire AVG for $1.3 billion.
AVG provides AVG AntiVirus Fre’ for Windows, AVG AntiVirus for Mac for macOS and AVG AntiVirus for Android for Android devices. All are freemium products: They are free to download, install, update and use, but for technical support a premium plan must be purchased.
AVG stopped providing new features for Windows XP and Windows Vista in January 2019. New versions require Windows 7 or later; virus definitions are still provided for previous versions.
AVG features most of the common functions available in modern antivirus and Internet security programs, including periodic scans, scans of sent and received emails (including adding footers to the emails indicating this), the ability to repair some virus-infected files, and a quarantine area (virus vault) in which infected files are held.
The patent pending LinkScanner technology acquired from Exploit Prevention Labs and built into most AVG products, provides real-time updated protection against exploits and drive-by downloads. LinkScanner includes: Search-Shield – a safe search component that places safety ratings next to each link in Google, Yahoo! and MSN search results; plus Active Surf-Shield – a safe surf component that scans the contents of a web site in real-time to ensure it’s safe being opened. Concerns regarding web analytics have made LinkScanner a controversial component (see “LinkScanner concerns” below).
When AVG 8.0 was first released, its LinkScanner safe search feature was shown to cause an increase in traffic on websites that appear high in search engine results pages. Since LinkScanner disguises the scans as coming from an Internet Explorer 6 browser when it prescans each site listed in the search results, we site usage logs showed incorrect and overinflated site visitor statistics.
The prescanning of every link in search results also caused websites to transfer more data than usual, resulting in higher bandwidth usage for web site operators and slow performance for users. AVG initially said that site administrators would be able to filter the LinkScanner traffic out of their site statistics, leaving the problem of excess bandwidth usage still to be solved. Pay-per-click advertising was not affected by the increase in traffic.
AVG Online Shield
AVG Online Shield is a feature designed to check files and ensure that they are safe. AVG Online Shield also ensures the safety of exchanging files via instant messengers and VoIP clients.
In response to complaints, AVG announced that as of 9 July 2008 “Search-Shield will no longer scan each search result online for new exploits, which was causing the spikes that webmasters addressed with us”, releasing a new build on that date that applies a local blacklist, then prefetches and scans only those links clicked on by the user
