Possible false alarm? Artemis!CF09A45B2660

I have read online that certain Artemis trojans that appear in a McAfee scan are not actually a virus but part of the McAfee program. McAfee "support" has tried to charge me $129 for the privilege of checking to see if it is in fact are virus or not.

McAfee cannot remove this from my system and the file path it gives me to remove it myself contains nothing (including no hidden folders as far as i can see)

Can anybody advise? I am not very good with computers but don't want to waste my time taking PC to a computer store if not necessary.

Also, does anybody know what these Artemis viruses actually do to the PC? Does is open my computer up to hackers?

Thanks in advance.

Support would normally steer you to their virus removal service which, as with other security software makers, is a chargeable service, but there's always a free alternative, see the last link in my signature below.

Artemis is the name McAfee gives unknowns that are detected and automatically submitted to the labs for analysis.

If you think it's a false detection, which sometimes it can be, then read here:

Unfortunately you can't believe everything you read on the Internet.

Artemis is the code name for the McAfee system which tries to detect malware much earlier than our researchers and data centers - it can be 5 to 30 days in front of typical detection methods.

Basically, whenever your machine sees a new piece of code, it hashes it (creates a mathematical "signature" of the code), pulls out some attributes, like whether the code is signed, 64bit mode etc, and then asks the McAfee brain in the cloud whether this file has been seen before.

Depending on who else is asking about that same thing, and the unique attributes of it, the McAfee brain (Artemis) may decide that it's unwise to run that program - That's when you get an Artemis warning message.

Your program may be ok, but it's reached a threshold that it's more than likely bad. We don't know anything else about the function of the file at this time, only that it matches the characteristics of other files which have turned out to be bad.  If the file no longer exists, then probably your system already deleted it. Maybe it was a temp file? What folder was it in?

If you want to do a deep scan of your system, you can use Stinger -
