I recently moved into a home and decided not to hook up the water line to my refrigerator. It was fine for a few weeks, but there appears to be a leak. Now the tube that flows from the water valve is leaking water. I'm not sure what needs to be fixed. Is it the water valve itself that needs to be replaced? I'm pretty sure the valve is turned off because it wasn't leaking before.

Sorry to have wasted people's time, but I did learn a lot. The technician came, and the answer was that the valve was defective. The inner parts should have been clamped tightly around the lip during the manufacturing process.
If the drip becomes a flood, it's not the cost of the water you should be concerned with; it's the water damage.
You say the leak seems to be coming from the valve itself, and your reasoning makes sense; if the toilet's dry it means the valve is turned off, so it's probably not any fitting beyond the valve stem. This means that the shutoff valve gasket, or the valve itself, has worn out or corroded and needs replacing. This happens over time; just like the flapper valves in the toilet and other elements of your plumbing, the shutoff valves corrode with acidic water, calcify in hard water, deteriorate in highly chlorinated water, and just plain wear out from use and water flow of any type over the years.
This is definitely something that nobody would think less of you for if you called in a plumber. However, it is DIY-able. You'll need to shut off the water to the whole house (there should be a shutoff valve near your water meter, wherever that is, and you may need a special tool to turn it off), then bleed the remaining water out of the interior lines (easy as turning on the faucet on the sink to cold, or flushing the toilet a couple times). With a bucket or pan under the valve to catch any remaining water in the line, disconnect the toilet from the valve and open the shutoff valve, letting any remaining water drain out of the line and valve. If this is a first-floor bathroom, there may be quite a bit to drain as the upstairs supply pipes will drain out as well. You can help it drain faster by opening a couple of faucets upstairs (providing a vent for the pipe stack similar to what you have in drain pipes). If it never seems to stop, you probably didn't completely shut off the outside valve.
Once the line is drained, you can work with the valve. The first thing to check is the fitting between the valve and toilet, since you have that apart anyway. Check the gaskets/washers on either side of the fitting. Some are compression fittings, and work by sealing a copper or nylon line against a ball inside the fitting; it won't work well if the end of the line or the ball has deep gouges, scratches, or is generally deteriorated. Most toilet lines are steel-braided rubber with threaded fittings, and usually can be easily replaced if necessary.
The next thing to check, and much more likely to be the problem, are the gasket washers in the shutoff itself. There may be one or two depending on the valve's design; one to seal off the supply line, and another to make the valve stem watertight. The valve stem should be going through a fitting screwed into the valve housing; unscrew that with a crescent wrench and you can take the whole thing out. You can usually also unscrew the handle from the stem and completely disassemble the valve stem. Clean off any calcium deposits from the washers, and inspect them for extreme wear or other deterioration. You can buy a bag of these washers for a couple bucks at your local hardware store. Reassemble the valve with the new washers, close the valve completely, and re-pressurize your house plumbing (make sure to turn off all the faucets you opened to drain the lines) to see if that did the trick.
If that didn't stop the leak, or the valve stem or body appears highly corroded and/or calcified, it may be time to replace the whole thing. With the house shutoff closed again and the lines drained, look at the valve's connection to the wall pipe. There should be either a compression fitting or a threaded NPT connection between the two, and in that case removing it simply takes your crescent wrench and some elbow grease. Some valves, however, are soldered directly on. If this is the case, I personally would stop and call a pro, but if you're handy with a soldering torch you can get the valve off yourself (careful you don't set the wall behind your toilet on fire). Then, simply take it to your local hardware store and buy a replacement with the same fittings; it should cost you about five to seven bucks. If the valve was threaded onto the wall pipe, get some Teflon tape as well. Use at least four wraps of the tape around the threads of the wall pipe (put it on in a clockwise direction, and stretch it a little to get it to mold to the threads), screw the valve firmly back on to the pipe, then re-pressurize the house again with the new valve closed (and all other faucets off) to check for leaks. If there are none, connect the toilet supply hose, open the shutoff, and make sure it still doesn't leak during and after the toilet fill-up.
If it STILL leaks, call a pro; you may have missed something, or done some damage in removing various parts.

If you are talking about the water supply to the fridge from the house the valve may have been bumped. If you can find the valve try and turn it off "lefty loose right tight" (I still have to remind my kids that sometimes LOL). If you find a Saddle valve that looks like this these are notorious for leaking at the connection point and dripping when not connected. the valve may need to be replaced. Hope that helps. At first I thought you were talking about the fridge itself but after re reading revised, putting both in just in case. If the water is dripping out of the tube on the refrigerator where you normally supply water to it, it will stop soon. Once a little air got into the tube the system started to empty out. To speed things up pull the water filter if it has one and trip the water in the door these will remove some water and allow more of the water in the system to drain out quickly. There is nothing wrong or to worry about.
