The first thing you should do is remove the link to the phishing page?
I think the link is ok as long as you don't download the actual script... Or I may be wrong...
To be safe, I would just remove it so others don't run the script on accident.
Put it between spoiler tags, and put alerts notifications around it, people wanting to help still like the link
You could go through a long process and remove it or just format, which is what I'd do.
the long process... is so long that I could spend months on it... and still see the mouse move on its own after I hook it back up to the internet... reinstalling is the only safe option...
