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 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.

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?
