Came home for Christmas today and my mom's laptop is having problems. She clicked on a video and i'ts changed the homepage, etc. I ran Malwarebytes, it found 7 problems and I removed them like the program asked. I ran Avira, it found two problems, moved them to quarantine.
I went into Chrome and manually changed homepage back to Google, yet some other page comes up. I completely uninstalled Chrome, ran Malwarebytes again, nothing found so I reinstalled Chrome. Still has the same problem. I'm afraid there's some kind of virus or rootkit that Malwarebytes isn't finding. Please help. Merry Christmas/Happy Holiidays.
