X means not found.
As seen from the table, we're fooled by the idea of extracting virus definitions files. Neither i32 files nor x86 files are capable of performing REAL updating!
Well, you might say that you used i32 files successfully. And I'd say that you're fooled! Why?
Because you overwrote the existing files, thus, you left the old "VIRSCANT.DAT" and added "UPDATE.TXT" which wouldn't be installed, of course.
If you want to believe me, do the following:
1- Go to: C:\Program Files\Symantec AntiVirus\Virus Defs\, and you'll be surprised! "UPDATE.TXT" isn't there. HUH!?
2- Get connected to the Internet, run LiveUpdate, and you'll be surprised! SAV downloads updates that are supposed to be, already, on your computer. HUH!?
What if you use x86 files? The worst, of course.
What if you delete all old files before pasting extracted files of i32 or x86? Installation of SAV will be interrupted asking for "VIRSCANT.DAT". This was exactly what happened to me!
There are worse events, but this is enough for now.
Solution? Maybe!
