Steps to reproduce the problem:
1. Visit this URL: http://www.pcsystemcare.info/error/lki45n4/
2. Try to click other tabs after the audio starts and the popup is visible

What is the expected behavior?
The user can still select other tabs as well as close the current tab.

What went wrong?
After looking at the page source it looks like the only thing really going on here is that the setInterval() callback to display an alert is being fired every 10ms. But since there is only ever 1 alert displayed at a time the process must be getting hung up processing and rejecting all the alert calls. But I could be totally off here.

It doesn't appear this site is doing anything else malicious other than trying to get the user to call an antivirus phishing scammer.

I've attached the page source in case the URL doesn't work in the future.

Did this work before? N/A
