Update: Oct 20th 2009 – Check out Windows 7 Compatible Antivirus Software
Matthew Arkin has listed some of the Antivirus software which are not compatible with Windows 7.
Antivirus software NOT compatible with Windows 7 Beta
- Windows Live One Care (ironical!!)
- McAfee Virus Scan
- Trend Micro Internet Security 2009
Got a heads up that these antispyware softwares are having problems-
- Super-Antispyware
Antivirus Software which are tested to be compatible with Windows 7 Beta
- AVG Free
- Avira Antivir [Get 6 month FREE license key HERE]
- Norton Antivirus 2009
- Avast antivirus
- Kaspersky antivirus
- NOD 32 Beta 4
- PCGuard Anti-Virus
- Microsoft Forefront Client Security (Enterprise)
- COMODO
The full compatibility of all of these programs is not guaranteed. Users are recommended to use one of the three endorsed programs on Microsoft’s Windows 7: Security Providers list. Other programs may seem to work, but are not fully compatible or functional.
Do let me know if you are aware of any other software which are compatible (or not compatible) as of now. I will update the list accordingly.
