History
The brand name AVG comes from Grisoft'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.
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. 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 110 million users have AVG Anti-Virus protection, including users of the Free Edition.
Issues
- When uninstalling AVG version 7 or 8 in Windows XP/Vista and attempting to install other anti-virus programs such as Kaspersky Anti-Virus or Norton AntiVirus, the latter programs will not install. Instead, they show an "incompatible software installed" error even if the uninstalled software has been removed using the control panel. This happens because software that updates and changes can add registry entries that were not added when the product was originally installed (therefore the uninstaller is unaware of the registry keys).
- A signature update dated November 9, 2008, crippled some computers, as it allowed the software to treat "user32.dll", a major component of Windows XP/Vista, as a trojan and advised users to delete it. Users who deleted the file in question were put on a continuous reboot loop. The problem was rectified a few days later with a new signature database and further safeguards were added to the product (270.9.0/1778).
- Towards the end of July 2009, a software update caused the program to inform users that iTunes was infected with a non-existent virus, Small.BOG. If users followed the recommended instructions, it would remove critical DLL files and corrupt the iTunes installation.
- An update of AVG 2011 resulted in Windows 7 64-bit systems being bricked, leaving machines in a continuous reboot loop. The update has now been removed.
