I have seen many folks and even some clients wondering if the AVG is going away from the free model. This is not the case. Grisoft is unfortunately trying to scare folks and they also don’t make it easy to find the free program. On http://free.grosoft.com it states:
New Free Anti-Virus
GRISOFT is announcing a new version of the AVG Anti-Virus Free Edition. This new 7.5 version with improved performance and full compatibility with the latest Windows Vista version is available. Users that are using AVG Free 7.1 will be provided with a specific dialog, within the next few weeks, with the opportunity to choose the right option fulfilling their needs. AVG Free 7.1 version will be discontinued on 15th of Jan 2007.
AVG is going to remain free at least through 2007 from what i have seen from Grisoft. You can find the download at the bottom of this page. Just install it over your existing AVG installation.
