Leading Internet security vendor Grisoft changes name to AVG Technologies

Global change designed to enhance AVG brand awareness

Grisoft, developer of the AVG family of security software products, today announced that it is changing its name to AVG Technologies. The renaming affects all subsidiaries around the globe:

• The parent company is now AVG Technologies N.V. • The Czech Republic-based company is now AVG Technologies CZ, s.r.o. • The US-based company is now AVG Technologies USA, Inc. • The Cyprus-based company is now AVG Technologies CY, Ltd • The UK-based company, already operating under the AVG name, will now be known as AVG Technologies UK Ltd.

All other contact and commercial data remains unchanged, including current Grisoft trademarks.

In October 2007, the Australia and New Zealand distributor, Avalanche Technology Group, set up a separate business called AVG (AU/NZ) Pty Ltd to manage and distribute the AVG range of Internet security products. Peter Cameron, Managing Director of AVG (AU/NZ) said there were no immediate plans to amend the company name to AVG Technologies AU/NZ Pty Ltd.

"The change in name is primarily intended to enhance awareness of the AVG brand around the world,” said J.R. Smith, Chief Executive Officer of AVG Technologies. "By aligning our corporate identity with our brand identity, we expect to significantly increase the effectiveness of our marketing activities and other communications.”

The AVG brand is widely recognised in the anti-virus and Internet security marketplace. A recent poll undertaken in the United States found that AVG was the third most widely recognised anti-virus brand after Norton/Symantec and McAfee. AVG is one of the 20 most-downloaded programs at CNet’s download.com site. Over the past several months, the AVG domains in multiple international markets (including Australia and New Zealand) have been acquired to ensure a smooth transition to the new corporate identity.
