Moved from a more than 2-year old thread. A lot of stuff changes in that time. Also transferred to the Artemis Forum which didn't exist back then. But in answer to your question there is no such thing as perfect protection. It is always wise to have one or two extra anti-malware tools handy just in case.
Someone from the Artemis section will be here soon hopefully, to help you.
I never expected the software to be perfect but I do consider when I send usage data, quaratined items, etc. to McAfee that they take action with an update. It does not seem that the Artemis issue is a new one. That said, I am still surprised to read your suggestion. Do you suppose my secondary software should be Norton Antivirus?! I would be curious if Symantec would make the same recommendation.
New variants of old infections appear almost daily so it isn't surprising at all. The fact that is reappearing is what matters which means you never got rid of it. Try disabling System Restore temporarily to see if that gets rid of it. Try disconnecting anything that is attached externally. Regarding the Artemis detection itself I can't tell you anything about it and am waiting for that department to spot this.
No of course I do not suggest you get a second antivirus, in fact that would be dangerous. Did you read the link I gave in my previous post or not? It doesn't suggest any such thing. Antivirus applications generally can only go so far at protecting you and do so for millions of infections, but there are some pretty clever ones out there that demand additional weapons, plus due care when surfing, downloading etc. and it's a good idea to keep all aspects of your system totally up date, even parts you may not use (such as Internet Explorer for instance), to prevent vulnerabilities.
The only results (8) from a Google search for Artemis!116749E2F595 are all from this thread. Is the Artemis identifier correct? If it is then I would suggest that the poster contact the labs to clarify this.
If the poster thinks this might be a false positive then he should follow the steps in https://community.mcafee.com/docs/DOC-1265
when did you last see a detection for this? We've not seen a hit on that file signature for nearly two weeks.
It looks to be a variant of this: http://vil.nai.com/vil/content/v_140927.htm
Ask the poster, Sam. I reckoned it might be a typo.
This was originally tacked on to a rather old thread so I branched it to it's own and altered the title/header, however, I checked the Artemis number was the same as they mention in the text of the first post.
