    Are you asking how to reinstall OS X Mavericks? If so, restart and press the Command+R keys to enter Recovery Mode and your Mac's Recovery HD. From the OS X Utilities Menu you can erase your Macintosh HD and Reinstalled OS X.

    Do you have any type of backup you can revert to?

    If not, before erasing and reformatting your HD for a clean install of your previous system, you need to, at least create a backup so you still have all of your important data backed up so you can copy it back to your new, clean system install.

    The erase, reformatting and re installation on your Mac's internal hard drive will erase everything including all saved data.

    You will have to reinstall all of your Applications, as well.

     

    Good Luck!

    It's extremely unlikely that you have a virus. Perhaps, at most, some adware that we could help you remove. If you describe your symptoms here, we may be able to give you advice that could help you solve the problem without resorting to such extreme measures.
