I tried some of solution given and it is not success(Renaming the "SoftwareDistribution" folder:)
Pls help me to recover this error.

I am experiencing the same error. Fix is upgrading Windows Update Agent on PCs to latest version 7.4.7600.226.

I think error is related to latest wsusscn2.cab file and PC with older Windows Update Version are not being able to parse successfully. I have several PCs with the latest verison that are scanning successfully
