Did you just get a pop-up from html.usagc.org and wonder where it came from? Did the html.usagc.org ad appear to have been initiated from a web site that under normal circumstances don’t use aggressive advertising such as pop-up windows? Or did the html.usagc.org pop-up show up while you clicked a link on one of the major search engines, such as Google, Bing or Yahoo?

Here’s a screengrab of the html.usagc.org pop-up ad when it showed up on my machine:

If this sounds like what you are seeing on your system, you probably have some adware installed on your machine that pops up the html.usagc.org ads. Contacting the owner of the site would be a waste of time. They are not responsible for the ads. I’ll try help you with the html.usagc.org removal in this blog post.

I found the html.usagc.org pop-up on one of the lab computers where I have some adware running. I’ve talked about this in some of the previous blog posts. The adware was installed on purpose, and from time to time I check if something new has appeared, such as pop-up windows, new tabs in the browsers, injected ads on web site that usually don’t show ads, or if some new files have been saved to the hard-drive.

html.usagc.org resolves to 137.135.80.241 and usagc.org to the 74.217.224.194 IP address. html.usagc.org was created on 2003-12-20.

So, how do you remove the html.usagc.org pop-up ads? On the machine where I got the html.usagc.org ads I had TinyWallet, BlockAndSurf and BrowserWarden installed. I removed them with FreeFixer and that stopped the html.usagc.org pop-ups and all the other ads I was getting in Mozilla Firefox.

BlockAndSurf was the adware that caused the pop-ups in my case. The pop-up ad was actually labelled with the adware name.

The html.usagc.org domain is attracting quite a lot of traffic, just check out the Alexa traffic rank:

The problem with this type of pop-up is that it can be popped up by many variants of adware, not just the adware on my system. I think that adware such as NewPlayer, SpeedCheck, CheckMeUp and SaferSurf can also be responsible for the html.usagc.org popups. And there are probably other variants too. This makes it impossible to say exactly what you need to remove to stop the pop-ups.

Anyway, here’s my suggestion for the html.usagc.org ads removal:

1. Examine what programs you have installed in the Add/Remove programs dialog in the Windows Control Panel. Do you see anything that you don’t remember installing or that was recently installed?
2. You can also check the browser add-ons. Same thing here, do you see something that you don’t remember installing?
3. If that does not help, you can give FreeFixer a try. FreeFixer is built to assist users when manually tracking down adware and other types of unwanted software. It is a freeware utility that I’ve been working since 2006 and it scans your computer at lots of locations where unwanted software is known to hook into your system. If you would like to get additional details about a file in FreeFixer’s scan result, you can just click the More Info link for that file and a web page with a VirusTotal report will open up, which can be very useful to determine if the file is safe or malware:

   

Here’s a video tutorial which shows FreeFixer in action removing adware that caused pop-up ads:
