All of a sudden I am seeing popup ads when I mouse over links on a few sites. Not all links are doing it however, only some.
Hi sallyanne,
From the symptoms you describe, it really sounds like you do have malware on your system. Either that, or you are visiting websites which use
IntelliTXT or some variation thereof. Rather than (or in addition to) running ADs, some websites convert keywords of their content to advertising links using "Text Enhancer" AD scripts, which is an attempt to trick you into clicking on a link that you think is there to give you more information, but it's actually an AD.
You're web browser can also be hijacked with one of these "
Text Enhancer" apps, which is likely what happened on your PC. The most common way to get infected is to install a Web Browser Add-on or Extension (or an app) that contains a toolbar, which does the hijacking. Things like "Coupon Companion" and other "Deal or Sales" toolbars, as well as various Download Managers, Video Player/Codecs are notorious for this kind of thing and I frequently clean them off of my clients' PCs.
You will want to check your Firefox Add-ons & Extensions to ensure none of these toolbars or other "helpers", have been installed. If you use a lot of Add-ons & Extensions and are not sure which of them might be responsible, disable all of them, then enable one at a time until you find the culprit.
From your Windows Control Panel, you should also check your "Add/Remove programs" or "Programs and Features" (or whatever it is they're calling it in your version of Windows) to see if some toolbar or another out of place app has been installed there.
Installing an AD Blocker alone doesn't really fix the underlying problem. Your AD blocker and malware might be fighting each other, which can be a drain on your PC's resources.
