Viruses are a big problem for Windows, as they continually cause a variety of problems for your PC. One of the biggest causes of the Runtime 13 error is the way in which many viruses tend to infect the core program files that Microsoft Office requires to run. This causes the files to become unreadable, leading Windows to be unable to process the commands you need, leading to it showing the error. To ensure this is not a problem, you need to be able to clean out all the virus infections that your system might have with a virus scanner. Our recommended virus scanner is a program called XoftSpy
