So yesterday I got on my computer and changed my desktop, the next day I got on my computer and it froze so I rebooted it. But when I did my desktop background had changed and when I went on google and a ton of searches had shown up that I hadn't made and all of them looked like this "gdyfpazjexc -site:youtube.com"
I don't know what these searches are but they definitely have some red flags. And when my computer crashed when I got back on it was running really hard. Ill take some notes in the comments section. If anyone could help me that would be great thanks!
