That send to link uses a protocol that is unfortunately blocked by many ISP's now so McAfee are thinking of ways to change it.
Meanwhile you would have to temporarily disable VirusScan in order to restore the file and subsequently submit it to McAfee.
To do that double-click the taskbar icon to open SecurityCenter
Click Virus and Spyware Protectiion
Click Real-Time Scanning
Click Turn Off and tell it 'Never' when it asks when to resume but don't forget to re-enable it after everything is done.
Then restore the file.
The easiest way to upload is to use McAfee's GetSusp tool, obtainable here: https://community.mcafee.com/message/198280#198280 which has the advantage of being able to upload large files if necessary, you'll see the Upload Tool tab in the interface.
