When you purchase a McAfee product and download it via mcafee.com/activate you expect it to scan for viruses and malware. However, due to any reason, it might start giving you glitches and not perform the real-time scanning task that it is ought to do. In that scenario, a user might think it to be a waste of money as well as time to invest in such a product.
Ways to fix the issue:
1. Use McAfee Diagnose and Repair tool
This tool is specifically available on the mcafee.com/activate website to fix issues with whatever McAfee products you are using. You just need to navigate to the official website and download the tool from there. After you have downloaded it, you need to run it on your device so that it could fix real-time issues with your product. After downloading it, do the following:
I. Click on the "Run" option
II. Double-tap on the file
III. Click "Yes" to allow it to make necessary alterations to your device
IV. Be sure that you do not close the windows that open
2. Reboot your system
3. Uninstall any third-party antivirus
Go to the McAfee antivirus and navigate to the Real-Time Scanning option. Toggle it on and then select PC Security. Choose the Run a scan option and then select Custom Scan. Deselect the paths of the large files which you made a note of. Then, click the Scan option again.
The other way to exclude a large file from the MacAfee Antivirus Scan not Working is given below. Launch the McAfee antivirus on your computer and toggle Real-Time Scanning on. Choose PC Security and click on Run a scan. Select the Scheduled Scans option and then choose Excluded Files and Folders. Here, you will have to choose Add File or Add Folder according to your requirement.
On the Browse window, navigate to the large file that you want McAfee antivirus to skip while scanning and then click Open. Now, the large file which you selected will be included in the Exclusion list.
