The url is: http://in.n3xtlvl . net/out/go.php

The tab just shows up with this url. Happened at least 3 times in last week. Just happened this morning.

Thanks LelandH

Sounds like a malware problem on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

I have MalwareBytes' Anti-Malware (Pro) and have done the long search and it found nothing. Might Microsoft Security Essentials find something Malware couldn't? My security system is avast! Antivirus (pay version).

Thanks, Leland

You need to scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
