Is the Internet Security Alert a scam website that wants you to buy software or install malware? This may be spreading through ads on Yahoo (sometimes called malvertisements).

Since you may see personalized ads on websites, and their URLs may be coded to work only on your computer, it's often difficult for researchers to get the same experience as you, and therefore hard to come up with a good blocking strategy.

One of your best defenses is to use an ad blocking extension such as: https://addons.mozilla.org/firefox/addon/ublock-origin/ With any content blocker, some sites may fail to load completely. If you trust the site, you can use uBlock Origin's toolbar button to make an exception and allow the blocked content to load.

Once you are on an attack site, you may need to use keyboard actions to "escape." I've seen users post example of sites using a combination of annoying techniques to force you to interact with them. These include:

1. Displaying a text entry dialog (username and password) that returns when you cancel it 2. Triggering a dialog asking if you approve resubmitting previously submitted information 3. Switching to full screen to block use of the menu bar, and when you move the mouse, doing it again 4. Displaying a large text box with instructions that returns whether you OK or Cancel it

Depending on the page you get, your approach may differ.

If you get the combination of #1-#3, try:

• Cancel the resubmission of data
• Press Esc several times in a row quickly to stop the authentication/reload loop
• Use a keyboard shortcut to close the tab, such as Ctrl+w or Ctrl+F4

Hopefully that will allow you to close the tab normally so that the crash recovery doesn't bring it back.

If you get #4, after cancelling it once or twice, a checkbox should appear at the lower left to stop the site from showing more dialogs. Check that box and click OK. Then try to close the tab normally.

Thanx for replying jscher. It's not that the internet alert wants me to purchase anything, there is a microsoft # it wants me to call to fix the problem.. I don't do that, I bring up the task manager & stop the process, but usually reappears when I'm on yahoo..I hurry & do my email there & get off as fast as I can as I do the rebooting of the browser several times while on the site..Is there a solution????

Hi fifth, my suggestions are the same for the fake support sites, good ad blocker plus knowing how to "escape" the con.
