I was wondering if anybody can help me with this problem. This morning when I went to the Big Fish site a pop-up - AGVZVWOF.com appeared. It won't go away and I cannot access the Big Fish site. If I use my Explorer browser, I don't have the problem. I ran some malware scans but they didn't pick up this pop-up. Should I just use my Explorer browser when I want to download from Big Fish? I haven't had any trouble with other sites when using my Firefox browser.

I did a Google search for "AGVZVWOF.com" and found this site, where people were reporting being redirected to AGVZVWOF.com when they tried to access eBay.

It turned out the problem came from an AVG Security Toolbar that installed itself inside their web browser. For some reason it though eBay was "unsafe" and blocked it.



Check your Firefox Add-Ons and Plug-Ins and see if there's an AVG Security Toolbar in there that you can disable.

This site has instructions for removal.

Thanks so much Jenny. While surfing the web I found that this pop-up also comes up when I go to the ebay site.
