Trojan.Zeroaccess.B Log Only

When I log into my computer the last two days I am receiving a message saying I have risks that should be addressed and to check my "Risk Log".  When I check the log it identifies the "80000000.@"  Trojan.ZeroAccess.B.  It says the action taken was "Log Only".  All the other associated files that the scan found were deleted.  Do I need to be concerned with the remaining "80000000.@" file that remains? I only get the alert once when I log in and my computer appears to be acting normal. I just don't want to have any security risks on my computer when doing business.

 

Thanks for the help!
