NEW PROBLEM trojan.brisv.A!inf

I wanted to start a new thread because I seem to be the only one with this problem

 

Norton pops up YET AGAIN and says I have the virus  trojan.brisv.A!inf

 

 I did all the steps with the removal tool a few weeks ago so I know what to do.

 

 

After I ran the tool last night it said

 No Virus found .......... Fine

 

I turn on computer this morning and norton pops up again and says I have it.

 

The Affected area is

1 File

Browser Cache

 

DETAILS

Restricted  Item Permission Required

 

I really don't know what to do any more.

 

Any advise woudl be appreciated.
