Did you just get interrupted by a popup ad from n121adserv.com? You are not alone. I also get the n121adserv.com pop-ups while browsing. Do the popups also find a way round the pop-up blocker in Google Chrome, Mozilla Firefox, Internet Explorer, Safari or Opera. Do the pop-ups appear on sites that does not advertise with pop-ups. Then read on...
Here's a screengrab of the n121adserv.com pop-up ad when it showed up on my system:
(I know, lots of watermarks. Have to do it to stop the copy-cats.)
Does this sound like what you see your system, you apparently have some adware installed on your system that pops up the n121adserv.com ads. So don't blame the people that owns the web site you were at, the ads are probably not coming from that site, but from the adware that's installed on your system.
I'll try help you to remove the n121adserv.com pop-ups in this blog post.
Those that have been spending some time on this blog already know this, but for new visitors: Some time ago I dedicated a few of my lab computers and wilfully installed some adware programs on them. Since then I've been monitoring the behaviour on these computers to see what kinds of adverts that are displayed. I'm also looking on other interesting things such as if the adware updates itself automatically, or if it downloads additional unwanted software on the systems. I first found the n121adserv.com pop-up on one of these lab systems.
So, how do you remove the n121adserv.com pop-up ads? On the machine where I got the n121adserv.com ads I had adware installed. I removed those adware programs with FreeFixer and that stopped the n121adserv.com pop-ups and all the other ads I was getting in Firefox.
The problem with pop-ups such as this one is that it can be initiated by many variants of adware, not just the adware running on my machine. This makes it impossible to say exactly what you need to remove to stop the pop-ups.
So, what can be done? To remove the n121adserv.com pop up ads you need to review your machine for adware or other types of unwanted software and uninstall it. Here's my suggested removal procedure:
Examine what programs you have installed in the Add/Remove programs dialog in the Windows Control Panel. Do you see something that you don't remember installing or that was recently installed?
You can also check the browser add-ons. Same thing here, do you see something that you don't remember installing?
If that did not help, I'd recommend a scan with FreeFixer to manually track down the adware. FreeFixer is a freeware tool that I'm working on that scans your computer at lots of locations, such as browser add-ons, processes, Windows services, recently modified files, etc. If you want to get additional details about a file in the scan result, you can click the More Info link for that file and a web page will open up with a VirusTotal report which will be very useful to determine if the file is safe or malware:
Here's a video tutorial showing FreeFixer in action removing pop-up ads:
