Claim that computer detected virus and to call immediately or they will shut down my computer so i harm other networks  claims vrus has sandboxed? browser     Message just pooped up on my computer and a guy was desparately saying call this number and agent would walk through  take control of my computr and fix it and unlock it  because my computer would shut down if i didnt call them

I had the same thing happen.  I blocked my # from then and called it.  They said it was Microsoft support.  Yet I have a Mac.  Hmmm.  Scam

Believe this is a scam.  They said its Microsoft support.

Got a popup window about support.Windows.com saying there is a Windows Warning Alert
Malicious Pornographic Spyware detected.
Seems scammy since I have MS Security Essentials installed.

Happened to me about 5:15 pm 12.21.17. HP laptop. Possibly it was from a contest webpage. "not secure"  About 3rd time in 2 months!!! Tried to copy pop up dialog box but kept going from dialog box to full page "emergency" and wanted me to hit "Escape full screen" button.  I turned off computer each time.  This time ran av programs, etc., but nothing new? If it happens to you don't hit any buttons. Just turn the power button off.  If someone else knows better leave a message.  Thanks!

In most cases, you can use task manager to shut the browser down, and then you should also clear the cache and cookies.  You should be using a browser that will not allow pop ups unless you accept them, block ads either on its own or with an ad on, and you should have Javascript and Flash turned off or only run with permission.  You might want to also install Malwarebytes and/or SpyBot, both are free and work very well, although SpyBot is a little harder to use.

Its a "Tech Support scam" Pop Up that you got from visiting a malicious website, an email or was tricked into downloading something that contained the Virus.
Here is a place that can help remove it:

If it still pops up or the removal program does not find anything, it could be a replicating virus that re-installs itself on each  system start up.
The virus is independent of your browser and only 'uses' it to activate the popup message in random website visits, generally from a list of 'keywords' programed in the virus app. Some of these are pretty well rooted into the Operating System files and require a Rootkit Removal program to thoroughly remove them. Its generally recommended to use more than one removal program to ensure it is removed.

I recommend  these for insurance they are removed:
Norton Power Eraser:

Malwarebytes Anti-Rootkit

Pretty much any program that threatens to shut down your computer or prevent access to your computer is a scam. It's a scare tactic.
