You may want to contact Technical support Chat found at the top of this page under Useful Links. Try another Virtual technician session and post the id so it can be referred to. Make sure you are up to date with all of your Microsoft updates. When you post your reply let us know what operating system you have XP or Vista and any other info you feel that might be helpful.
Could you please try to capture the error message underneath the Fix button so that we could diagnose the issue and fix it for you.
The next time , when McAfee says Am I protected NO (before clicking FIX ) capture the error message displayed under the fix button and post it here.
Also try to run Mcafee virtual technician from http://mvt.mcafee.com and post me your session id so that I could review you installed files .
