Mcafee claims hostassignment.exe is a trojan Artemis!15B30775AE5F

I can roll out Teamviewer 12 because Mcafee claims there is a trojan and therefore the file is automatically deleted by OnAccessScan

cairns ran C:\Windows\explorer.exe, which attempted to access xxxxxTeamViewer_Assignment.exe. The Trojan named Artemis!15B30775AE5F was detected and deleted.

Re: Mcafee claims hostassignment.exe is a trojan Artemis!15B30775AE5F

Hi dcairns,

Thanks for bringing this to our attention! This is actually a "false positive" on the part of McAfee - they are falsely reporting the file as being a trojan when, in fact, it is not.

If you check the file at VirusTotal.com (direct link to the report here), you'll see that only McAfee's antivirus engine is reporting the file as being malicious. The other 55 antivirus engines correctly report the file as being safe. It's also noteworthy that the date of McAfee's virus signatures there is "20170108" while the dates of the other engines are all "20170116" - ie. McAfee's signatures are old.

In any case, we have already reported this false positive to McAfee earlier today, and we expect them to fix the issue as soon as possible.

For more info on false positives, have a read of our Knowledge Base article on the topic here:
