Microsoft Makes AVG Security Products Available Directly From Windows Security Center in Windows Vista.

GRISOFT Is First to Offer Free Antivirus Protection to Users of Upcoming Windows OS

MILLBURN, N.J. -- GRISOFT today announced that Microsoft is making AVG Anti-Virus 7.5 and AVG Anti-Virus Free Edition available via Windows Security Center as a Windows Vista security solution. The solutions are available in the latest release of the Windows Vista[TM] beta program and will be available in the commercial release. The programs can be accessed via this link: http://www.microsoft.com/athome/security/update/windowsvistaRC1AV.mspx

Antivirus protection is vital for computer users. Now with support for Windows Security Center in Windows Vista, using AVG Anti-Virus Free Edition and the latest commercial release is even more convenient. AVG products utilize a low level of computer resources. This feature is now even more important as personal computers and networks today run more and more different applications and services simultaneously, which can slow computer performance.

"Partners are critical to the success of our platform and the security of customers," said Ben Fathi, vice president, Security Technology Unit at Microsoft. "GRISOFT has worked closely with us during their recent launch of their 7.5 security programs to assist Windows Vista beta users, and this partnership helps support our goal of protecting customers, providing choice and enabling ISV innovation."

GRISOFT's Windows Vista-ready products include AVG Anti-Virus 7.5 and AVG Anti-Virus Free Edition. These AVG products offer protection against a variety of computer and cyber threats like viruses, Trojans, adware, dialers, keyloggers and worms. These products also include automatic updates and a single, user-friendly interface.

"We're very excited to be working with Microsoft to provide their and our users with protection for the current Windows Vista beta program and upcoming launch of the new operating system," said Larry Bridwell, vice president for communications at GRISOFT. "Our security programs are ready for the Windows Vista launch and making sure that users have the best security protection and great services available for their PCs."
