I know this is giving you re-assurance which is bad but at the same time, I feel like I should educate you. People don't get arrested for looking at or searching for illegal content. The people who get arrested are the ones who download it and then someone finds it on their computer and reports them. Either that, or they get involved in a police sting operation with webcams and stuff or they upload the material online. Simply viewing the material or searching for it will not get you into trouble. It's not like your ISP is monitoring what you are Googling and then report it to the police. No, it's always after the crime has been committed (terrorism for example) that the ISP will go through and see what was being viewed or downloaded, and even in that case they can't always find it. The people who get in-trouble are the ones who run the websites or download and collect (and then get caught) with illegal material.
