Is it the antivirus protecting me?

You can have all three installed, but I would not suggest you run them simultaneously. This can cause system performance issues as well as potential conflicts.

The most important protection you can ever get is Common Sense. You can have the meanest security arsenal in the world and it would not prevent malware infections if you don't apply common sense in protecting your PC. Watch and think before you click, download, plug in a thumbdrive, or visit suspicious websites. This will help save you a whole lot of hassle.
