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

Here’s how the cn.tatami-solutions.com pop-up looked like when I got it on my system:

In my case, the loading stopped with a “500 Internal Privoxy Error“. Did you also get the error message, or did you see an ad?

Does this sound like your story, you presumably have some adware installed on your machine that pops up the cn.tatami-solutions.com ads. There’s no use contacting the owners of the website you were browsing. The ads are not coming from them. I’ll do my best to help you with the cn.tatami-solutions.com removal in this blog post.

I found the cn.tatami-solutions.com 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 anything new has appeared, such as pop-up windows, new tabs in the browsers, injected ads on website that usually don’t show ads, or if some new files have been saved to the hard-drive.

cn.tatami-solutions.com resolves to the 46.105.156.70 IP address and tatami-solutions.com to 46.105.156.78. According to DomainTools and YouGetSignal’s reverse lookup service are the following domains located on the same server:

• bycontext.com
• contextual-mobilesdk.com
• contextual-sdk.com
• offers.bycontext.com
• view.contextualyield.com
• www.bycontext.com
• www.offer-dynamics.com

So, how do you remove the cn.tatami-solutions.com pop-up ads? On the machine where I got the cn.tatami-solutions.com ads I had gosearch.me, SmartComp Safe Network, Live Malware Protection and Windows Menager installed. I removed them with FreeFixer and that stopped the cn.tatami-solutions.com pop-ups and all the other ads I was getting in Mozilla Firefox.

Judging from Alexa’s traffic rank, cn.tatami-solutions.com is getting quite a lot of traffic:

The problem with pop-ups such as this one is that it can be launched by many variants of adware, not just the adware running on my computer. This makes it impossible to say exactly what you need to remove to stop the pop-ups.

Anyway, here’s my suggestion for the cn.tatami-solutions.com ads removal:

The first thing I would do to remove the cn.tatami-solutions.com pop-ups is to examine the programs installed on the machine, by opening the “Uninstall programs” dialog. You can open this dialog from the Windows Control Panel. If you are using one of the more recent versions of Windows you can just type in “uninstall” in the Control Panel’s search field to find that dialog:

Click on the “Uninstall a program” link and the Uninstall programs dialog will open up:

Do you see something suspect in there or something that you don’t remember installing? Tip: Sort on the “Installed On” column to see if something was installed approximately about the same time as you started getting the cn.tatami-solutions.com pop-ups.

The next thing to check would be your browser’s add-ons. Adware often show up under the add-ons menu in Chrome, Firefox, Internet Explorer or Safari. Is there anything that looks suspicious? Something that you don’t remember installing?

I think most users will be able to identify and remove the adware with the steps outlined above, but in case that did not work you can try the FreeFixer removal tool to identify and remove the adware. FreeFixer is a freeware tool that I started develop about 8 years ago. Freefixer is a tool designed to manually track down and remove unwanted software. When you’ve identified the unwanted files you can simply tick a checkbox and click on the Fix button to remove the unwanted file.

FreeFixer’s removal feature is not locked like many other removal tools out there. It won’t require you to purchase the program just when you are about to remove the unwanted files.

And if you’re having troubles figuring out if a file is clean or adware in FreeFixer’s scan result, click on the More Info link for the file. That will open up your browser with a page which contains more information about the file. On that web page, check out the VirusTotal report which can be quite useful:
