Judging by the path of the file that is 'infected' it looks to me like it is one of the files from a system restore backup. This means that the anti virus program will not be able to remove it. I am pretty sure that it also means that as it should not be active. I had the same problem with ME but using Quest Second Chance rather tahn the built in System Restore.
If that is the only place that it was found then at some stage your anti virus program must have got rid of it.
This is what I did. 1. Made a new system restore point 2. Found the file in Windows Explorer and right clicked on it. Choose properties and looked at the date the file was created. 3 Went into system restore and deleted the appropriate restore point. 4. Re-scanned and all reference to it was gone.
If you cannot determine the date then you may have to delete the oldest restore point then re-scan to see if the file is still present. repeat if necessary.
Having read the info in the link above it would seem that turning off system restore DOES remove all the files that it created at the various restore points. That means the infected file has gone- permanently. However, so have all your other restore points so make another quick if you have not already done so.
My method was a little cumbersome but I still had several unaffected restore points available.
