Registry Errors

The latest office updates were installed day before yesterday and now I am
getting 7 errors reported by my Norton System Works 2005 when it does a
"Scan". The errors are as follows:
The key"Detfile\Defaulticon,"refers to a missing icon, "C:\program
files\support.com\Backup\MI\Misc.Exc,6"
I won't retype all the path of the remaning errors as they are in the same
folder. But the errors are as follows:

Fadfile
Nickfile
Ostfile
Pabfile
Pstfile
Rwzfile.

My questions are, did the latest dnload load cause these errors? I "NEVER"
had these errors appear before the "Office Updates" the other day?
Do I need to be concerned about these errors? If so, how can these errors be
"Fixed".
I saw where there are 154 sub folders in the C:\Program Files\Support\Backup
folder. Do ALL these folders need to be there for a reason or can I delete
these folders?

Please advise.

Thanks.
