How do i stop popup claiming my PC has been infected?

It could also be random "fly by malware". If you are using Firefox, add a program called NoScript, that will stop any malicious scripts from running on a page. There is a similar program for IE, but I'm at a loss to recall what it is. Maybe someone can help me out on the name?

Were you talking about AdBlock IE? With google this is the only thing I can find for IE that mentions anything about NoScript.
Adblock IE

Everyother thing regarding NoScript and IE8 on Goolge says the NoScript function is included.

Hi, idahosurge.

I suggest that you check for vulnerable third-party software on your computer -- Java and Adobe products have had critical security updates due to vulnerabilities. In addition, with Java, you need to check add/remove programs to make sure you don't have any old versions still installed, as didn't get the update process correct for many years.

To check if your system is missing security updates or has insecure applications, install Secunia Personal Software Inspector or, alternatively, visit Secunia - The Leading Provider of Vulnerability Management and Vulnerability Intelligence Solutions . The Secunia Software Inspector runs through your browser with no installation or download required and does the following:

• Detects insecure versions of applications installed
• Verifies that all Microsoft patches are applied
• Assists you in updating your system and applications

In addition, as long as you are not having a problem opening .exe's and desktop shortcuts aren't missing, it wouldn't hurt to do a thorough cleaning of temp files:

Download TFC to your desktop

• Open the file and close any other windows.
• It will close all programs itself when run, make sure to let it run uninterrupted.
• Click the Start button to begin the process. The program should not take long to finish its job
• Once its finished it should reboot your machine, if not, do this yourself to ensure a complete clean

A month ago on an XP PC and last night on this PC I tried to shut the popup program down and all that did was get my PC infected.

Unfortunately, your attempt at closing the pop-up was actually permission to install. Never click anywhere on the fake A/V pop-up box. Instead, use the keyboard combination Alt + F4 to close it.

Thanks Corrine, I updated Java to 6.30 and updated Acobat 9 Pro. I had already ran Secunia. I use CCleaner so running TFC was not necessary.

One thing NOT to do is click anywhere on the pop-up. Including the X. Close the tab or IE.

I have had this happen when I am at Yahoo's website so it does not have anything to do with questionable websites.

Sorry to disagree but Yahoo is one of the worst offenders for malware infections. They sell ad space and don't control the contents. Any third-party hack can put what they want in the ad, including scripts, and Yahoo doesn't filter them. It got so bad Yahoo and anything related is blocked on my PCs. Also be sure you have the latest version of Adobe Flash. And don't allow Flash to run on all web pages--Be selective. It's another "open door" to your PC.

Thanks for the information regarding Yahoo, now I know!

Adobe Flash has been upgraded, thanks!

Hi,

I also got that stupid fake "win 7 antivirus 2012" thing and I got rid of it by using Spybot Search&Destroy software. You can find it here fro free:

Default File Type Associations - Restore

Try to download it from a good computer and try to run it in admin mode. Good luck.

As Carwiz said, never click anywhere on one of those popups. That's like inviting a vampire into your home. Without the invitation, they can't enter.

When you see a popup, try to close the browser to clear it. If that option is disabled by the malware, then right-click the Taslbar, open Task Manager, and try to stop the browser under the Applications tab. In some cases, the malware delivery program (popup) just recreates itself. When that happens, try rebooting the computer to avoid infection. If you run across a situation where rebooting is also blocked, just hold in the power button and shut the computer down. The potential for damage is lower with a forced shutdown than it is from the infection.

Another options to close the popup is the keyboard command Alt + F4.
