Hiya Mike,
I ran into this one and your idea to rename it is probably fine.
I found a well rounded answer on the Microsoft Technet site from Ronnie Vernon.
This is his answer which helped me greatly.
original context
"This is a common problem with that RSS feed synchronization task. Here is the fix.
Open the Task Scheduler.
On the View Menu, select the 'Show Hidden Tasks' option.
In the left side menu, select 'Task Scheduler Library'.
In the Center section, right click the 'User_Feed_Synchronization' task and select Delete.
Exit the Task Scheduler.
Next, select Start / Accessories. Right click 'Command Prompt' and select the 'Run As Administrator' option.
Click 'Continue' on the UAC prompt.
In the command window, type the following command.
msfeedssync enable
Press ENTER.
This command will replace and refresh the 'User_Feed_Synchronization' task.
This will not affect the RSS Feeds you are subscribed to."
