I'm having trouble running a full scan in Symantec Endpoint.  The problem I'm having is that when I start a full scan, the scan runs for more than 20 minutes, but I get a message indicating that the operating system stopped the program. 

The os is vista home premimum service pack 1.

 I have previously downloaded the removal tool to completly remove endpoint and did a reinstall.

Here is the operating system error message

 Title bar: Microsoft Windows

Text: Syantec AntiVirus stopped working and was closed.  A problem caused the application to stop working correctly.  Windows will notify you if a solution is available.

Buttons: Close

 Any suggestions / guidance?  

 thank you.

John
