It sounds like you have some antivirus app installed, which you don't need. You don't need any 3rd party antivirus app to keep your Mac malware-free. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released 10 years ago. You cannot infect your Mac simply by visiting a website, unzipping a file, opening an email attachment or joining a network. The only malware in the wild that can affect Mac OS X is a handful of trojans, which cannot infect your Mac unless you actively install them, and they can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.
You don't need "cleaner" or "maintenance" apps like MacKeeper to keep your Mac running well, and some of these apps can do more harm than good. Some remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process.
It looks like the AntiVirus process is, indeed, a part of MacKeeper. Check to see if you have the following:
I highly recommend you fully uninstall MacKeeper.
Or you can follow the directions linked in the 2nd post, using ‘zeobit’, ‘mackeeper’ and ’911 bundle’ as your search terms. That will fully remove the app.
I highly recommend you completely uninstall MacKeeper, as it is at best unnecessary and at worst, potentially problematic. It has a terrible reputation in the Mac user community.
