I have had the same problem.
I am using Avast 6.0.1125 on a Compaq HP PC running Win XP-Pro-SP3 as the O/S, all my programmes are kept up to date with upgrades.
My repair, worked for me:
Using Windows “Search”, look into your hard drive, “C:”, or whatever drive letter designation, and find the Acrobat files, “Soap.api”, and “Updater.api”.
Determine the exact complete files paths, such as:
C:\Program Files\Adobe\Acrobat 7.0\Acrobat\plug_ins\Soap.api
C:\Acrobat pro7.0.8 Setup\program files\Adobe\Acrobat 7.0\Acrobat\plug_ins\Soap.api
C:\Program Files\Adobe\Acrobat 7.0\Acrobat\plug_ins\Updater.api
C:\Acrobat pro7.0.8 Setup\program files\Adobe\Acrobat 7.0\Acrobat\plug_ins\Updater.api
Copy and paste the above full-path designations to notepad.
Then…
1) Open Avast
2) Click "REAL-TIME SHIELDS" on left
3) Click "Expert Settings" on right
4) Click "Exclusions"
5) Click "Add"
6) Click "Browse" and navigate to the folder containing the soap.api file, which is the "false positive", or simply copy and paste each of the above complete file paths into a new exclusion-entry line, and make sure that all three tick boxes, “X”, “R”, and “W” are checked
7) Click "OK"
8.)Re-enable all Avast shields, if you had them disabled, (which you probably did, in order to repair Acrobat.)
9.)Open Adobe Acrobat… it should be OK now.
