SEP v12 Crashes Windows 7 with teefer2.sys BSOD

This issue has been solved. See solution.

March 6, 2010. What a mess! I installed SEP Small Business v12 on a new Dell Latitude E5500 with Windows 7 Professional. SEP updated and then the computer rebooted. BSODs and endless reboots with teefer2.sys problems. Couldn't uninstall Network Adapters with "teefer2" in Device Manager; disabling all Symantec services and programs in MSCONFIG didn't help. Can't uninstall SEP in Safe Mode.

I finally got the computer running again by renaming \windows\system32\drivers\teefer2.sys to ...teefer2_sys, disabling all Symantec services and programs with MSCONFIG and rebooting in non-Safe Mode. Then unstall would remove SEP. I am afraid to reinstall SEP and may just give this employee - and future computers with Windows 7 - McAfee Enterprise 8.7i which seems to work just as well based on a recent minor virus (from Facebook) outbreak.

If someone has a way to SAFELY and RELIABLY install SEP v12 with Windows 7 Pro, please let me know at jseigel@21stcenturyservices.com. THANK YOU!

 The older version of SEP 12 are not compatible with Windows 7..So make sure you are using the version 12.0.1001.95.

The most helpful part of entire Symantec connect is the Search button..do use it.

I am in the process of downloading the Symantec Protection Suite SBE 3.0 via the fileconnect link (87% complete now).

If I download the version 12.0.1001.95 will it work with the Symantec Protection Suite SBE 3.0 that I am currently downloading and also, will I be able to install it successfully on Windows 7 64 bit PCs because this is a major factor for me.  Most of the PCs in my organisation are Windows 7 64 bit OS.

Finally, what is the link to download the version 12.0.1001.95?

Regards.
