    It can be some kind of virus infection in your system. You have to check that properly. Boot your pc in safe mode first and scan with a good antivirus. You can download a trial edition of various free antivirus and test with them one by one. Even in the trail you get complete features to clean your system. I think going for norton will be good enough. Or you can also use Avira.

    This error is not related to any virus. It is associated to old programs installed in your system. I got the same issue when I was trying to use a old accounting software on my system. But it did not worked well. I had removed that tool and the error was gone. So just check in your system if there is any old program running. Just uninstall that. The error will stop.
