As the Windows 7 Operating System launch date is nearing(October 22) almost all the major software vendors are making sure that their products run on Windows 7. As a general rule all the applications that run on Windows Vista should run on Windows 7.
But the applications like anti-virus programs, firewalls and others that work hand-in-hand with the underlying Operating Systems needs to be reengineered for every specific operating system.
Microsoft Windows Security page has listed the anti-virus programs that are already tested and proven as compatible with Windows 7. They include Norton, AVG, BullGaurd, GDATA,Panda, Kaspersky( I’m using this s/w for the past 2 years), McAfee, Trend Micro, webroot and F-Secure.
This list covers almost all the major antivirus vendors. But others like ESET Nod32, Avast, PCGuard Anti-Virus and Microsoft Forefront Client Security are yet to be added to this list.
