I had the same problem but neither of the solutions about malware or reinstalling worked.

The problem for me was a permissions issue since the reader would open fine on the administrator accounts but not the user accounts.

The system was windows xp SP3.

The solution: (needs to be done from an account with admin rights)

1.
Start -> run -> "regedit"

Navigate to "HKEY_LOCAL_MACHINE\HARDWARE\SOFTWARE\Adobe\Acrobat Reader"

Right click on "Acobat Reader" and select "permissions"

Select users and give "full control"

Click advanced and select "Replace permission entries on child objects..."

Apply and ok

Close regedit

2.
Open an explorer window and navigate to "C:\Program Files\Adobe\Reader 11.0"

right click on "Reader 11.0" and select properties > security tab

select users and give "full control"

Click advanced and select "Replace permission entries on child objects..."

Apply and ok

3.
Open an explorer window and navigate to C:\WINDOWS\system32

right click on "System32" and select properties > security tab

select users and give "modify rights"

Click advanced and select "Replace permission entries on child objects..."

Apply and ok

Hope this helps
