**8. Hex editors and PE viewers**

Depending on the complexity of the malware, it may be difficult to detect in an image file. Viruses and worms can be difficult to detect, but you can use a hex editor or a PE viewer to check an image's data section. This can also be helpful when detecting malicious code in an image file. You can view the hex data of an image file by opening it in a hex editor. This will show you any data that's been added to the image file, such as hidden code. If you are working with an EXE file, you can use a PE viewer to see the data that has been added. You can also use a debugger to debug the application and find any malicious activity.
