I'm surprised apple doesn't have some kind of virus scanner thing already on it. I have windows, and it has windows defender so I can virus scan at least.
Well depending on the computer you have you may have Windows Defender on it, which can do virus scans. If you don't, you should talk to your parents about getting a virus protection system like Norton or AVG or McAfee or something.
uh try doing a virus scan on your computer, see if it finds anything. If it does find something have it try to clean the virus. If that doesn't work then...well you have an issue
