Please don't attach samples of possible malware. As you don't indicate the name of the detection and whether or not this is while using Consumer or Enterprise software I've moved this provisionally to Malware Discussion > Home User Assistance. Hopefully someone will pick it up.
Here's an article I did on this situation: https://community.mcafee.com/thread/2016
I am inclined to agree with Ex_Brit, until the here-in mentioned file has been cleared, it is not wise to post the "Possible" infection. I say this due to the fact, after doing some searching using the above "Supposedly False Positive"
I got some hits that were detected as various realtionships with the "Sasser Worm" Dating as far back as 2004. This infection(if it actually is) hides with-in the "lsass.exe" process, and can also be present when the normal Windows process(services.exe) displays.
One primary Red Flag, is if you notice that the "Services.exe" is spelled "ServiceS.exe" It spreads thoughout the system and infiltrates and infects other users through (Emails). Rather than giving the name,I will insert a link , that Security Vendors list their individual names for the detection, to include McAfee if in case this is the same process in Question.
I might add that this primarily effects Windows XP...
