Hi I had recently unistalled my AVG 7.5 Antivirus utility. Due to certain problems after that i performed a System Restore(the day after uninstalling AVG)
Due to this AVG still showed up as being installed but would never run. When i tried to install OneCare AVG AntiMalware showed up as a conflicting program. When prompted to Remove this application, the uninstallation obviously failed as the necessary files were already missing. Hence installation was unable to proceed.
