If it occurred after the removal of viruses, it could be that you have deleted a file needed to run a program. This can sometimes occur if a large file is infected, and removed from the system. Often the error occurs when starting the program. As most of the runtime errors, this happens because of a series of processes is corrupted or missing files is interrupted. In this case, the OCX file, which is necessary to open the program. These files are located in the Windows system directory.
The solution to this problem may be affected quite clear, and it is in most cases. Indeed, if the file is missing OCX source of the problem, then replacing it should solve the problem.
