Malicious pop-up alert: fake malware infection notice

Several people have reported that they have had a very real-looking fake malware infection notice pop up on their computers while they are web browsing. It appears in the lower right corner and may even say that it is Microsoft Security Essentials. However, it says to call an 800 or 877 number for help, which is how we know it’s fake.

It may be accompanied by a fake “blue screen of death” page in the background. There have also been reports of it using sound to try to intimidate people into calling.

If you are concerned that your computer has been infected with malware, please contact your local IT staff right away. Contacts:
