What's with Adobe Acrobat Reader 7?

I'm trialling Comodo's Firewall and keep getting a popup warning almost everytime I use my IE6 browser or Outlook - it warns me about Adobe Acrobat Reader 7 altering Windows applications - see below.

What's going on here, its becoming annoying to say the least!

System is using Windows XP SP2 and I have MS Office 2007 beta installed.

 

What happens if you click the 'remember action' bit at the bottom?
I'm trying Comodo too but don't use Adobe, instead I have Foxit Reader.

 

Does Foxit work without any problems? I get very fed up with Adobe taking an age to load and phone home, although that is blocked. Also seems to stay in memory when it is not really needed.

 

It repeats every time even when I've told it to remember the action.
I'm so fedup I've removed Comodo as it has other problems - keeps closing randomly.
I'm now tryialling KIS 6.0 instead of Nod32 and Comodo - no problems of a similar nature so far.

 

Foxit works really well. Never had a problem with it.

 

Tried it out and it is neat, however unlike Acrobat it does not get called by the browser when you click on a PDF link. Uninstalled Acrobat and set Foxit as default, rebooted but still does not get called. Any idea?
