How can I tell if my macbook has a virus?

There are no OS X viruses; that's how you can tell. 😉

What Kappy say's is true. However if you feel like you must have some virus protection try ClamXav. You can install and run it to check for malware/viruses. the nice thing about ClamXav is once installed you can right click on any program or document and check it for malware/viruses. It also has an app called Clam Sentry which you can run in the background which will give you live monitoring of your system for potential threats. And ClamXav is free. If this gives you peace of mind, then by all means. Hope this helps!

How can I tell if my Macbook Pro has a virus?

There are dozens of pieces of malware for a Mac, unfortunately for them the only way they can get on your Mac is if you install them or get tricked into installing them.

So be careful and trust the source of anything you run or install on your Mac. Don't trust sites that say "you need this..." If you need a plug-in like Flash, then Google for Flash instead, don't follow a link from the site that links you, it could be a "trojan".

It's a good idea to create another Admin user, log into it and turn your first Admin user into a General User which has less elevated priviledges. Whenever you alter certain folders or install programs, it will need a admin name and password.

Also just because your running a Mac, doesn't mean your safe to visit the back alleys of the Internet with impunity.

There are web sites that will crack a Mac, if you want a extra layer of protection on those sites, I suggest using the free VirtualBox virtual machine software to run a ISO of Linux Mint (ideal). Take a "snapshot" when you first install it, then when your finished, revert the virtual machine back to the snapshot.

Good Luck 🙂

More to the point, why do you think it has a virus?

There's no way to be absolutely sure, but you can't do better than to use ClamXav as suggested above. It will find any of the few known instances of Mac malware. It won't find malware that's unknown or very new.
