Hi everyone big fan of the show! But I have been having some problems with my roommate. He can pretty much get on my computer any time he wants when I'm not home(which isn't a big deal). And he installed a trojan or something on my computer which allows him to shut down my computer any time he wants and he's done some other weird stuff too. I didn't really care that much until yesterday when I was working on a lab report for a long time, and I hadn't saved it. He thought he'd be funny by shutting down my computer. I lost my entire report I was so pissed. So I downloaded an antivirus(I never had one cause I'm very good about the websites I visit and the e-mails I open) and removed it.
So I turn to you guys, I know what he is using is pretty simple cause he's not a big computer geek, I know a fair amout about computers but nothing about hacking. I wanna put something on his computer to be able to do the same stuff to him, I search the internet but did not really find anything usefully other hten programs to remove trojans. I can get on it pretty much every day when he is in class so it just needs to be something that will run in the background that he won't notice.
Thanks for the help!
