4. How Do Security Software Conflicts Affect IDM's Functionality?

IDM's operations can be hindered by conflicts with certain firewall or antivirus software. For instance, after updating IDM, some security programs may block its internet access due to changes in the executable's size or behavior. This can prevent downloads from starting or completing. To resolve such issues, users may need to adjust their security software settings to allow IDM's processes. Detailed configuration guides are available for various security applications.
