2. Download "Windows defender" from microsoft website and scan ur pc for the spywares/adwares.
3. Click on Start>Run and type msconfig.
4. In the Startup tab uncheck the below option
Manager "C:\Documents and Settings\Administrator\Application Data\Adobe\Manager.exe"
OR
IF UR USER ACCOUNT NAME IS NOT ADMINISTRATOR BUT "MOHAN" (SAY) THEN
Manager "C:\Documents and Settings\MOHAN\Application Data\Adobe\Manager.exe"
Unchecking the above option cures the problem temporarily.
U need not worry of the registry entries as far as ur system is working fine and u have latest Adware/Spyware.
Hope the above suggestion solves ur problem.
