This is what I'm dealing with: http://i.imgur.com/8cdnaJT.jpg
The hyperlink ads are inserted onto nearly every webpage I visit, after the page loads. It happens on both Firefox and Chrome, both of which have different adblockers, and both adblockers don't recognize them as ads from the website. It happens in safe mode (with networking) as well. I've scanned with Panda, Malwarebytes, and Spybot, in safe mode, all of which found nothing. Checking over the HijackThis log didn't show anything either, but I'm not very well versed in this.
They all started appearing after I installed a plugin called "Aspera Connect" to download some files for work. It didn't seem malicious, but I've never had anything remotely like this before I installed it, and couldn't find any other reason for them to appear. I did some searches but it's hard to pinpoint exactly what this is called, since "ads appear on webpages" is a terrible thing to search for with any specificity.
Running Windows 7. Any ideas would be appreciated.
