Anti-Virus Guard (AVG) is a family of anti-virus and Internet security software for the Microsoft Windows, Linux, Mac OS X, and FreeBSD computing platforms, developed by AVG Technologies, a publicly traded Czech company formerly known as Grisoft.[1]



The brand AVG comes from Bernard Schwartz's first product, "Anti-Virus Guard", launched in 1992 in Czechoslovakia. In 1997, the first AVG licenses were sold in Germany and UK. AVG was introduced in the U.S. in 1998.[2]

The AVG Free Edition helped raise awareness of the AVG product line.[3]

In 2006, the AVG security package grew to include anti-spyware, as AVG Technologies acquired ewido Networks, an anti-spyware group. That same year, Microsoft announced that AVG components would be available directly within the Windows Vista operating system.

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 released in March 2009.

According to AVG Technologies, over 106 million users have AVG Anti-Virus protection, including users of the Free Edition.[4]


Versions for Windows desktop clients

AVG Technologies provides a number of products from the AVG range, suitable for Windows 2000 onwards. In addition to this, AVG Technologies also provides Linux, FreeBSD, and most recently Mac OS X versions of the software. AVG Anti-Virus 9.0 is available in free and commercial editions. AVG 9.0 has identity theft protection through a partnership with Intersections Inc., AVG 9.0 also adds white listing, behavioral protection and cloud operations to their signature-based blocking. The software adds the Resident Shield, firewall, and identity protection modules. The LinkScanner component has been improved to cut phishing threats further.[5] Version 9 was the last version compatible with Windows 2000.

For desktop protection of PC's running Windows, the AVG solutions include:

AVG Free Edition has previously been responsible for popup ads advertising the non-free versions of AVG Anti-Virus and AVG Internet Security, which claim to provide more comprehensive levels of protection.[7][8] AVG Anti-Virus 8.5 Free Edition users are now also subject to a daily pop-up advertising campaign for a "recommended upgrade" to AVG Internet Security. A "manager" on the AVG free version forum states that this advertisement appears once per day for one month each year.[9]

All versions of the AVG products, excluding AVG Anti-Rootkit Free Edition (now discontinued), are compatible with the 64-bit edition of Windows.

Versions for servers

AVG Technologies also sells AVG anti-virus and Internet security solutions for web/file servers or email servers running either Linux, FreeBSD or Windows.

AVG for Linux/FreeBSD

With version 7.5, AVG Technologies is providing a solution for FreeBSD for the first time. AVG Technologies has incorporated spam detection in addition to virus detection for Linux/FreeBSD software.[10]

Mobile Security


A joint project of AVG and Israeli start-up Zbang, Multimi is a free Windows desktop and iPad app for organizing and sharing content between multiple inboxes, social networks, calendars, and media albums.[11]

AVG PC TuneUp®

AVG PC TuneUp is an application designed to speed up the computer by removing files that may slow down the operating system and optimizing some of its settings.


AVG features most of the common functions available in modern anti-virus 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/chest" 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.[12] Concerns regarding web analytics have made Link Scanner a controversial component (see "Link Scanner Concerns").


When AVG 8.0 was first released, its LinkScanner safe search feature was shown to cause an increase in traffic on web sites 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, web site usage logs showed incorrect and overinflated site visitor statistics. The prescanning of every link in search results also caused web sites to transfer more data than usual, resulting in higher bandwidth usage for web site operators and slow performance for users.[13] AVG initially said 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.[14] Pay-per-click advertising was not affected by the increase in traffic.[15]

In response to complaints, AVG announced that as of July 9, 2008 "Search-Shield will no longer scan each search result online for new exploits, which was causing the spikes that webmasters addressed with us",[16] releasing a new build on that date that applies a local blacklist, then prefetches and scans only those links clicked on by the user.[17]

Resource requirements

AVG usually supports several products and usually the two latest versions of each, as well as the AVG Beta Program. Additionally, each product is available for only certain operating environments ("System Requirements").

Version 2013 of AVG (Basic,Internet Security....) released in 2012. it gives high security with no cons and has a new outlook... but takes little time to be installed.

Version 2012 of AVG (Basic, Internet Security, ...) released in 2011. AVG also advertise] 3rd party services to remove what AVG doesn't/can't.

Version 2011 of 5 AVG products (Free, Business, Home) for AVG & AVG Internet Security, ...) (A fake version has also appeared in this version as a virus. The fake version may take internet explorer to pretend to warn them that a site contains malicious software and redirect people to a secure less sites in the internet. It can block access to task manager and other legitimate software and misleads people into paying the full version of the fake software. It also shuts down the system with Netpumper. It's mostly recommended to copy and paste the URL so they can avoid an unexpected shutdown. This rogue version cannot be uninstalled normally, they must use any malware removal in order to remove the fake AVG software and it's malware that doesn't normally install with the software.) [18]

Version 9 of AVG (Free, Internet Security, ...), released before June 2010.

Version 8.5, both AVG Anti-Virus and AVG Internet Security require at least 256 MB of RAM for the computer as a minimum.[19][20] The comparatively high use of paged physical RAM has led to crashes with some software, such as the Half-Life 2 series.[21]

Version 7.5 of AVG Free requires a Pentium (or compatible) CPU with 300 MHz and between 64–256 MB of RAM, depending on operating system (at least 64 MB with Windows 9x, at least 128 MB with Windows 2000 or newer, with more RAM recommended).[22]
An additional caveat with version 7.5 in Windows XP, which is a multi-user system that allows more than one user to be logged in at a time, is that scheduled scans ran as separate processes, which created a situation in which there were two scheduled scans, one in each active account, running simultaneously and causing heavy hard disk throttling and considerable system lag. This fault was finally fixed in version 8.0 of the program.

During its version 6.0 run, AVG was known for its conservative resource requirements . The AVG Anti-Virus Professional Edition required 16 MB of RAM and 20 MB of space on the hard drive.[citation needed]



AVG Anti-Virus was certified by ICSA Labs.[30] AVG Antivirus Free 2012 was selected as PC Magazine Editors Choice in the free antivirus category.[31] AVG Anti Virus Free 2013 received a 5 out of 5 star rating on Cnet's Download.com.[32]
