To kill these ads when they start, you need to understand what is happening and know a few windows shortcuts.

With faster computers that have more memory it is now possible to have several programs running at once. You can also have several Internet browsers open at once. When unwanted ads start to appear, here is what is actually happening:

• you click through to a webpage
• that webpage then opens another webpage underneath itself, in a new browser window
• this new webpage is given coordinates that puts it off your viewable screen, so that you can't actually see it to click on its close window "X" box
• the new webpage contains some programming code that in turn opens up one or more unwanted ads
• each time you close one ad, the window opens or "spawns" another ad window

The ads usually promote technology products and services, or pornography.

You need a few shortcuts - not the shutdown function - to close down these unwanted ads.

• First, you need to use the Alt-Tab shortcut, which lets you toggle between open program windows. While depressing the Alt key, toggle the Tab key to move between windows.
• When you move from one browser window to another, but see no visible indication that you have moved to a different browser window, you are likely on the window that contains that ad spawning code
• Before moving to another window, you need to shut down this browser window. To do this, click Alt-F4.
• Now you should be able to go and close down individual ads, without new ones appearing!

Alt-Tab followed by Alt-F4 is a fast way to shut down unwanted ads.
