Norton anit-virus tells me I have a virus they call Download Trojan which is located in a file identified as C:Windows/System32/Browsela.dll. Norton cannot repair, quarantine or delete the file, nor can Ad-Aware of Spybot. I have tried to use Windows xp to delete it but even in safe mode it will not do it. I even tried a utility called GiPo with no success. Anyone know how I can delete this file?
