Unless you installed NAV *after* the date to which you restored your
computer, it should still be there after a System Restore. If it is
missing or broken, I'd suspect infection by one of the viruses that
damages antivirus programs. You might try scanning in Safe Mode with a
standalone av program like Stinger. Stinger looks for about 30 of the
most common viruses. Of course, it isn't a substitute for a
full-featured av program, but it is great for fixing things. Here's a

If you need more help, please repost and include some information about
your system, what the original problems were that caused you to do a
System Restore, and what you've already done to troubleshoot.
Happy New Year,
