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.
