Any help? Norton Finds Trojan zero access but power eraser and remove say I am clean

Any opinions?


My Norton Internet security after a complete scans says im infected with Trojan zero access inf 4 . It tells me I must use a manual removal. The link told me to try Norton Power Eraser as well as Fix zero access. I downloaded these one at a time and ran and both told me my system was clean.

 

Do I have a Trojan hidden some where that these don't find?

 

Is there any way I can find out ?

 

I've heard this is a nasty little bug and if I am infected need to take care of it immediately
