P2P Dangers - File Sharing Can Compromise Your Computer's Security
Peer-to-peer file-sharing programs appear to be a godsend: they allow you to swap digital files with others who have the same file-sharing software. Thousands of people use peer-to-peer (often called P2P) programs to exchange music, videos, movies, games, and software. But P2P programs are seemingly synonymous with trouble.
First, there are the well-publicized copyright infringement issues that arose when Napster, the first widely used P2P program for exchanging music files, became wildly popular in the late 1990s. Other examples of P2P programs are Kazaa, Morpheus, eDonkey, and Gnutella.
Less well-known, but perhaps more significant, is how using P2P programs can expose your computer to viruses, worms, Trojan horses, adware, and spyware, and even expose you to identity theft and fraud. How can these things happen? A P2P network allows users with the same file-sharing program to access files stored on each other's computers without the typical network interaction with file servers. This makes file sharing quick and easy, but these are unsecured Internet connections unprotected by firewalls, making them prime targets for hackers and virus writers.
It's easy for virus writers to attach malicious code to an innocently titled file that resides on a file-sharing network. In fact, the infamous MyDoom virus that wreaked havoc on e-mail systems worldwide in 2004 was initially spread in this way by unknowing users of the Kazaa file-sharing program.
The same goes for adware and spyware. These unwanted programs could be attached to an otherwise useful file downloaded from a file-sharing network, exposing you to a flood of unwanted spam, ad pop-up windows, and web browser hijackings.
Even worse, a skilled hacker can gain access to your entire hard drive through a file-sharing network, exposing you to identity theft and fraud. A hacker can do this by using access to the files you intend to share on the file-sharing network to gain access to personal files not intended for public use. If you have information such as Social Security numbers and credit card information on your computer, the potential for identity theft and fraud is very real.
Here's how to protect yourself on P2P networks:

Ask The Help Desk - Why Is My Computer Screen Wallpaper Distorted?
Question: Sometimes I save images off the Internet for wallpaper on my computer screen. However, the images I save quite often look very distorted when I stretch them to full screen. How can I avoid this?
Answer: You are probably running into a couple of problems. The first is that of proportions. If the image you are grabbing from the Web isn't proportional to your screen, it will look distorted when it's stretched. Remember, your screen format is rectangular having horizontal and vertical dimensions. So if you save an image that is much more vertical than horizontal, the image will look "fat" once it is fitted to your screen.
The other problem is that most images found on the Web are not a high enough resolution to be used for wallpaper. Many computers, for example, are set to a resolution of either 800x600 pixels or 1024x768 pixels. When grabbing an image off the Web, the image needs to be close to the same size as the resolution found on your screen in order to appear undistorted. If the image is only 250x100 pixels, for example, there just won't be enough pixels to fill your computer screen in an undistorted manner, unless of course you are using a very small screen.
Note that most site owners have copyright restrictions regarding their site's content (text and images) so you must first get permission before grabbing an image to use as computer screen wallpaper.

Short Tutorial - Images Saved On Your Computer Screen As Repeated "Tiles"
As the FAQ in the "Ask The Help Desk" section above explains, it can be difficult to grab images off the Web to use as wallpaper without the images appearing distorted on your computer screen. Rather than trying to stretch pictures to fit your computer's screen, an alternative is to "tile" your selected image. This process saves the picture repeatedly in rows on your screen as a background. The result may be cluttered but probably preferable to the distorted alternative.
To tile an image as your screen's wallpaper when using a PC and Internet Explorer as your browser, simply right-click on the chosen picture and select "Set As Background."
If you are on a PC and using the new Firefox browser, right-click on the image and choose "Set As Wallpaper." When the "Set Wallpaper" dialog box appears, look for the "Position" menu. It will list "Stretch," "Tile," or "Center" as options. Choose "Tile" from the list. Click on the "Set Wallpaper" button. The background of your computer screen will change to multiple rows of the picture you selected.
If you get tired of using this image, right-click on your PC's desktop and choose "Properties." With the "Desktop" tab selected, choose the wallpaper you want from the list that appears. Click "Apply" and then click "OK." (This works whether using Internet Explorer or Firefox as your browser.)
If you are using a Macintosh running OS X, right-click your cursor arrow on the image (if you have a two button mouse) or click on the image while holding down the "ctrl" key (if you have a single button mouse) and select "Download Image To Disk." Next, go to the Apple menu then drop down to and select "System Preferences..." Click on the Desktop & Screensaver icon and click on "Choose Folder" in the left hand pane of the window. Click on "Desktop." The picture you downloaded to disk should be there. Click on it to select it and then click on "Choose." Next to the preview picture you'll see a button that says "Fill Screen." Click on it and four choices will appear: "Fill Screen," "Stretch to fill screen," "Center," and "Tile." Choose "Tile" and then close the window.
