exclude characters when importing from csv

I am trying to write a script that can modify windows permissions for server shares. With one script I am exporting the server shares to a csv, then with this script I am importing the 'path' of the share. The problem is that default shares like C$ and even printers get imported, and that interferes with my script to run.

I need to explicitly deny permission to certain users and the default admin shares come back with a 'permission denied' error, even from an administrative prompt. So the they are getting in the way and I need ideas on how to exclude them.  

Here is an example of the path:
Path
C:\Windows
C:\
Canon MX490 series FAX (Copy 1),LocalsplOnly
Canon MX490 series Printer (Copy 1),LocalsplOnly
Fax - HP Officejet 5740 series,LocalsplOnly
HP Officejet 5740 series,LocalsplOnly

C:\Windows\system32\spool\drivers
C:\share
C:\Users

My thought is that I could import both the Name and Path and exclude any rows that contain the character $.
Example of Name and Path columns:
Name      Path
ADMIN$      C:\Windows
C$      C:\
Canon MX490 series FAX (Copy 1)      Canon MX490 series FAX (Copy 1),LocalsplOnly
Canon MX490 series Printer (Copy 1)      Canon MX490 series Printer (Copy 1),LocalsplOnly
Fax - HP Officejet 5740 series      Fax - HP Officejet 5740 series,LocalsplOnly
HP Officejet 5740 series      HP Officejet 5740 series,LocalsplOnly
IPC$      
print$      C:\Windows\system32\spool\drivers
share      C:\share
Users      C:\Users

Another thought would be to create a variable, that contains the common shares like C$, D$, IPC$, Print$, etc and telling my script to exclude any rows that match that list, but I am not sure how to go about doing that either. Lot's of options here, just looking for the best one.
