On my brother's computer he kept getting a message from his anti-virus software about something called JS downloader agent. He kept moving it to his virus vault but never did anything about it '
slughead'. He eventually asked me about it. I had never seen it before so I looked it up on a virus encyclopedia. It showed that it was a trojan. So I deleated it. He has not seen it again. I still do not know just what it was. Was this a trojan that could actually do harm to his computer, or was it nothing?
