I don't know what you used to remove your virus but norton sucks and the virus can still hide on your
computer. I use AVG and absolutly love it. No annoying pop ups like norton has.
http://www.grisoft.com/doc/1 check it out cause its free, however you do have to remove all of norton.
if you go to "run" and type in "regedit" they hide in there too. You then go to Hkey local machine - software - microsoft to
windows to current version and see if the file is hiding somewhere in there. Like I downloaded the trial of estimate and did the thirty day thing and returned the software and uninstalled it from my hard drive and low and behold it was still hidden in there. (they like to stick stuff in these folders and hide it to know if you already downloaded it before) also....if you right click my
computer on your desktop and click mangage, (in the box to the left click) services & applications, services they hide in there too and you can delete them forever....
try that avg though, like i said i love it and it's like number 1
