getting symefa64.sys is corrupt of missing on Win7 Dell E6500. Have Norton 360, upgraded to this years version, working fine for a couple of months until this morning's error. Cannot boot (not even in safe mode) recovery keeps identifying this path/file as the problem:
c:\windows\system32\drivers\n360x64\1505000.013\symefa64.sys I was able to get a command prompt and the file is in this folder. I do not think I have a Win7 recovery disk so what do I do now. I see others had this problem in 2009, 2011, but not recently. Can you assist?
