How to disable "Your Computer is infected" Ads/Popups from our Blogs?

Our visitors are very annoying by "Your computer is infected/virus alert" pop-under's/pop-ups via Internet explorer browser mostly. We disabled software promotion from the settings on popads.net and is there anything we can do for this to completely disable?
We contacted popads support but it doesnt work yet...

One of our visitor says: "I clicked on anything a new window would appear on my browser saying my PC was infected and a screen would pop up and not close. Had to shut down my PC twice just to get Explorer to close."

Website : This Link and this link (NSFW - XXX) .: It (The software popup) appears when you click somewhere on the site.

Those are coming from popads? That's sad... I thought it's possible to use them with adsense on site :/

Yes i think they are coming from popads.net but Im not sure we also using plugrush pop-under's. Disabled software promotion on popads.net and waiting for the feedback.

These annoying popups are created by rogueware installed in your computer. Get rid of them using utilities such as Malwarebytes and 'Spybot search and destroy'

Which adnetworks causes these software/virus alert popups/popunders? Is it popads.net, plugrush or juicyads? Which one?

No need providing your link cos afterwhat your visitor experienced, i doubt anyone would visit that url. I suggest you disable any of the ad networks you suspect. Test.. if the problem persists, disable the other

It only shows to the United states visitors and for internet explorer i guess.

Dont want to disable all of the advertisements. But we can find out which caused this.
