Did you just get interrupted by a pop-up ad from o.checkerlive.com claiming that you should update your Flash Player?. You are not alone. I also get the o.checkerlive.com popups while browsing. Do the pop-ups also circumvent the pop-up blocker in Google Chrome, Mozilla Firefox, Internet Explorer or Safari. Then read on…

Here’s how the o.checkerlive.com pop-up looked like when I got it on my machine:

Does this sound like what you see your machine, you probably have some adware installed on your machine that pops up the o.checkerlive.com ads. Contacting the owner of the website would be a waste of time. They are not responsible for the advertisements. I’ll do my best to help you remove the o.checkerlive.com pop-up in this blog post.

Those that have been reading this blog already know this, but here we go: Not long ago I dedicated some of my lab machines and intentionally installed some adware programs on them. I’ve been monitoring the behaviour on these computers to see what kinds of advertisements that are displayed. I’m also looking on other interesting things such as if the adware auto-updates, or if it downloads and installs additional unwanted software on the computers. I first spotted the o.checkerlive.com pop-up on one of these lab computers.

o.checkerlive.com resolves to the 198.7.56.101 IP address. o.checkerlive.com was created on 2015-01-14. The “Flash” download was signed by Smooth Funnel.

So, how do you remove the o.checkerlive.com pop-up ads? On the machine where I got the o.checkerlive.com ads I had PriceLess, PriceHorse, OfferBoulevard and SpeedCheck installed. I removed them with FreeFixer and that stopped the o.checkerlive.com pop-ups and all the other ads I was getting in Internet Explorer.

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

Anyway, here’s my suggestion for the o.checkerlive.com ads removal:

1. What software do you have installed if you look in the Add/Remove programs dialog in the Windows Control Panel? Something that you don’t remember installing yourself or that was recently installed?
2. How about your add-ons you installed in Chrome, Firefox, Internet Explorer or Safari. Anything in the list that you don’t remember installing?
3. If that didn’t solve the problem, 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 computer. 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:
