After clicking in a fake "download here" button in a webpage for film downloads, a computer has got infected with what I believe to be an adware. I have located the file, VirusTotal gives this analysis of it.
One wierd thing that makes me uneasy is that when I launch Norton's complete check, it freezes after a random number of files checked (~18k, ~30k).
I am familiar with NIFO, but it is really necessary in this case?
