I have just read through McAfees Virus Database and it says "Use current engine and DAT files for detection and removal. Removal requires removing the entry in the SYSTEM.INI file and restart to MS-DOS mode to delete the file manually from the Windows and Windows\System folders." So yo may need a person in your local area who knows how to use MS-DOS boot yourself.
If you have SpyAxe, then you have possibly had this message appear:

About the Adware version McAfee explains the adware as:
"This is not a virus or a trojan. It is detected as a "potentially unwanted program". This is an anti-spyware application claiming to remove unwanted malicious spyware programs. In an attempt to get you to purchase the full version of the product, it may be installed by a Trojan (see Spyaxe ) which will display fake warnings (some appearing to be Microsoft Security Center or Windows Update warnings) which may lead you to believe that your computer is infected with malicious spyware programs. In order to clean or delete any files labeled as Malicious spyware・ you must first enter a valid serial number to activate the full version or click on the Buy Online・button and purchase the full version. "
So in general SpyAxe acts like its a spyware remover, but it just claims random things as spyware (which truely aren't) and then tells you that you have to go on their website to pay for the full version to have it 'remove the malicious objects' which it actually doesn't.
So.. its just a big money scandal kinda thing. It's just an unwanted program. McAfee doesn't really consider this a threat at all though
