Adobe Reader X 10.0.1 stops working

Question

I have Adobe Reader X 10.0.1 on my computer running windows vista with comcast norton security suite installed.  Every time I open a pdf file or open the reader x program within 1-2 minutes I get an error message stating that "adobe reader has stopped working" and it prompts me to uninstall the program and reinstall the program.  I have reinstalled the program several times but I continue getting the same error message.  If act quickly I can print or save the pdf file but if I don't do anything or even just open the Adobe reader program and wait I get bumped out of the program within 1-2 minutes.  What can I do?
Here is a screen capture of what happens after 1 minute when I open the reader x program

actually, the other thread has one that solves mine:

from this:
<quote>launch Reader and uncheck the option 'Enable Protected Mode at startup' in Reader Preferences->General. Close and re-launch Reader.
<unquote>
I did as well:
<quote>Can you kill AdobeCollabsync.exe from Task Manager and clean the following folders (but do keep a backup of all files):
C:\Users\<user>\AppData\Roaming\Adobe\Acrobat\10.0\Collab
C:\Users\<user>\AppData\LocalLow\Adobe\Acrobat\10.0\Synchronizer?
