First, we would have to know what entries you have in the virus chest. Can you list them here? You can also right click the entries in the chest and select scan. It is possible that some entries might be false positives.
As far as the HJT entry is concerned, it will not matter when you fix it since the entry has no file association which means the entry is useless. After doing this, I suggest again that you follow Tech's advice above.
