NIS 2012 keeps finding the trojan.zeroaccess virus and tells me it's fixed and to reboot my computer. Whenever I do that, it tells me it's found the same virus and it's fixed and to reboot my computer. A complete scan found the bad file in C:\windows\assembly\gac\desktop.ini and continues to find it there every time I scan. First, I can't find such a subdirectory; my c:\windows\assembly folder only has one empty subfolder, called "download." I have hidden files and system files set to not be hidden, so I'm confused as to where this is. Second, how can I stop it from returning every time I turn on my computer? I ran the NPE, but it found nothing except some startup files that I know to be okay.
