The virus probably made changes to your registry to keep you from running
AV software and removing the program from memory (denying access to
msconfig, regedit, etc).  To really remove any virus you need to use one of
the virus removal tools on the web.  I assume that you know which virus you
removed so you should do a search with this virus name and download the
removal tool from any of several sites that provide them for free.  Note
that you may have to use another computer to download since some of these
viruses also block your access to AV websites.
