Just the fact that you are seeing those ads probably means you are already infected in some way.
Nah. They're probably just Adsense ads. Google has no qualms about hawking malware if that's what the highest bidder is selling.
I get driver download Adsense ads constantly, even on Linux machines, if I've been searching for drivers, reading an Adsense-enabled page dealing with drivers (like a forum page about a driver conflict, for example), or downloading drivers onto my own or someone else's machine using my office Internet connection. I know for a fact that some of the sites being advertised are laden with malware, adware, crapware, and grayware. Until someone complains, Google doesn't care.
Neither does it matter whether or not I used Google search to get to the page about drivers. The Adsense code on the content page is enough to identify and make note of my interest. So is Google Analytics code or calls to Google fonts or APIs in the page code. By visiting any page containing any of the above, on any computer or device on my network, I'll insure that I get those ads on every other computer on my network. I'll even get them on my Blackberry when I'm using it on my office WiFi, and then even when I'm not on WiFi, once Google has associated the interest to the BlackBerry's browser and Device ID.
Just for ****s and giggles, I went to an Adsense-enabled site on my sister-in-law's phone the last time she was here and using my connection. Sure enough, she was getting ads for whatever Google had decided I was interested in that day based on my computer activity.
In short, the mere presence of the ads doesn't mean the machine is infected. It just means that to call Google a whore defames real whores the world over.
I'd download rkill, malwarebytes, and rogue killer from bleepingcomputer.com. Run rkill, then install malwarebytes and run it. Then rogue killer.
Great ideas if you think the machine's rooted. Nice choice of easily-available tools that are unlikely to break anything, too, along with a trustworthy source site. I think it's a bit overkill if the only evidence of a problem is an Adsense ad (if that's what it is); but hey, better safe than sorry if there's any doubt.
Be EXTRA careful when downloading anything from anywhere. Even the best legitimate sites now seem t have extra "download" buttons all over them that are thinly disguised ads for crapware.
I agree completely. And a lot of the "download buttons" are Adsense ads.
