It would help to know which version of McAfee but I'll post the instructions for disabling VirusScan Home version for last year's version and this year's. But really you should submit those files for analysis and possible clearance by the McAfee Labs.
First disable your virus protection:
To temporarily turn off VirusScan 13 - 2009 do the following:
Double-click the taskbar icon to open Security Center
Click Advanced Menu (bottom left)
Click Configure (left)
Click Computer & Files (top left)
You can disable VirusScan in the right-hand module and tell it for how long.
Then click the Restore button (left & assuming it was quarantined) & restore the item.
In VirusScan 14 - 2010 double-click the taskbar icon to open SecurityCenter
Click Virus and Spyware Protection
Click Real Time Protection
Click the Turn Off button and tell it for how long to stay that way.
Then click Navigation (top right)
Click Quarantined and Trusted Items (below) & restore the item.
Send the file to Avert for analysis:
Email file to: firstname.lastname@example.org
When submitting samples via E-mail all samples must be packaged in a .ZIP file. When creating this .ZIP file, it is important to understand that the .ZIP can be no more than 3 megabytes in size and can contain no more than 30 files.
Additionally, any .ZIP file created must be password-protected using the password "infected" (minus the ""). Failure to follow these guidelines will cause your submission to be rejected.
