I have exactly the same problem. Since yesterday all of a sudden (during dinner time) the internet connection (WiFI connection) was away. Cannot find the apparatus anymore. USB ports are not recognized as well. McAfee does not work, right click on the icon does not show any info.
I found the DAT file (created yesterday 25,5 hrs ago), approx. just before the problems started.
I deleted the dat-file, but cannot find svchost.exe
And since no internet connection, nor USB recognizing, I cannot copy easily this file from another working computer.
Is a malware version about mcafee going around? Or has it to do with the last "nice" updates of McAfee.
