Groovicus has the correct answer.....

If you have to come here to ask how to find your enemy then you probably don't have the level of skill to protect yourself properly when you do. That being the case, you create two victims rather than one.

Best to use the old adage of the First Aider, (responder), here..... Don't put yourself in danger.... Add to that Sun Tzu.... Know your enemy...... You are missing stuff in both areas IMO.... Thus, format the box, reinstall from trusted media, protect it for the future and move on..... It isn't really worth the grief......
