If you want to get rid of it and are sure that it is an unwanted object then follow these instructions. As you haven't stated what version of VirusScan you have I'll include both 2010 and 2009 consumer versions.
For VirusScan 14 - 2010 - which has a shield-shaped icon in the taskbar, double-click that icon to open SecurityCenter
Click Navigation at top right
Click Quarantined & Trusted Items in the list below.
If it is VirusScan 13 - 2009 which has a square taskbar icon, also double-click to open SecurityCenter
Click Advanced Menu (bottom left)
Click Restore (left)
Click Files (right).
Remove whatever is in the Quarantine folder and it will be gone from your machine. Do NOT use Restore unless you wish to reinstate it.
If something is misidentified as an infection McAfee wants to know about it.
This thread will explain how to get around it in order to report the file to McAfee.
