You're going to have to be more specific as to which MacBook you have. You haven't really provided us with info that's needed to try to help you. For now... try rebooting the MacBook while holding down the Command plus the R key. That should get the MacBook into recovery if the hard drive or SSD is still OK. And by the way, you do not have a virus since there are none in the wild that can infect your MacBook. Malware yes, viruses no.

And please use a proper thread title so that people know what u want. Help for MacBook in a MacBook Forum is not very informative cos every second thread is about helping. the search function can't read ur mind

Regarding search: If u google mac + reinstall u gain that exact answer.
If u google mac + help u get ???
