So I made a mistake and ran a dubious executable program downloaded from the internet. I was making a dvd and I didn't know how to download videos from funnyordie.com, so I went out on a limb and tried Wondershare Allmytube. It did what I wanted but it seemed really sketchy and it made my laptop start working so hard that my fan kicked on without any user input, so I turned off the wifi and uninstalled it right away and now I'm paranoid that I'm a part of some botnet or someone's got my saved chrome passwords.
