Try booting into Safe Mode and running McAfee there, if it detects it it should be removable. To run in Safe Mode simply right-click the folder and select Scan or right-click your McAfee icon by the clock and select Scan.
In this mode all you will see if some activity in that notification area icon. Hover over it for a progress report.
If that doesn't help I suggest running either Hijackthis or DDS as suggested lower down the last link in my signature below, Then post the log as instructed on an approriate forum, We don't analyse them here due to work load.
Alternatively McAfee has a professional virus removal service but that costs money, so you may wish to try the above first.
If it keeps coming back then it's a cloaked infection, probably a rootkit. Either that or you're being re-infected by something like P2P or Skype (both of which have been used to deliver BitCoin mining malware). There are posts a-plenty about dealing with this on other forums, especially the Malwarebytes forum. You may need to ask there or on BleepingComputer for specialist advice if Ex_Brit's suggestion about Safe Mode doesn't deal with the problem.
Try running RootkitRemover first to deal (if possible) with anything that's modified the MBR.
This would be a good case to run GetSusp to find any unknown software that may be reinstalling malware or unwanted programs.
If GetSusp or the other above suggestions do not work for you, post back and I will point you to other solutions to detect software starting up with your computer that may be downloading and installing malware/PUPs over and over again on your computer.
Oh if you have win8 getsusp might give you an erroneous list of suspicious fiies till they fix the issue in a week or so.
I realy want to thank everybody for their great effort to get rit of this nastey malware/virus thing.
I tried all the solutions, but not of them really did it for me.
Than I turnt over to ComboFix who spotted the program that caused all the troubles and removed it.
After a safe mode scan with McAfee, who picked up the last trojan, that for some strange reason was not picked up by ComboFix, I am glad to say my machine is clean again.
Again thanks for all the good ideas, which at the end pointed me to the solution as described above.
