Don't download whatever it's asking you to, it will probably really screw your system up. Download a scanner and scan you computer. You can find some good ones here http://www.snapfiles.com/Freeware/securi...

Also, check your history on your browser to see what happened. Confront your brother if it was porn if you want to, but make sure to change your online preferences about questionable sites so they can't be visited in the future.
