Even to this date, my ISP (broadband) wants me to install their troubleshooting software, and even when I first got the service, they said that they had a toolbar that needed to be installed. I called them liars to "their face" (so to speak, I was on the phone). For broadband connections, as well as dialup, you don't need the software that ISPs want you to install. Both types connections can be installed manually within the network area.
So presuming that you don't have spyware, malware, adware, etc on your computer in the "classic sense", most likely these popup stuff is coming from software that your ISP had you install, again presuming that they had you put software on your system.
You should use Firefox, because they have good add-ons that prevents things. I tested AVAST Internet Security. The Antivirus is great, I'm using it (the free version), but their Internet Security Firewall is substandard.
I use to use Comodo IS, but left it, not because it was bad, per se, but the Interface was too convoluted, and they force the user to answer too many questions. For instance, I might have said that program "X" was AOK to run with program "A" starting it. But later it would ask it again. I'd tell it that program "X" was an allowed program, but even in their configuration area, under "run", they had only "ASK" and "BLOCK", no allow. In order to prevent the questions from coming up again and again, the user had to go in manually and put an exception in. This should have been done automatically, when the user said it was an allowed application. For COMODO users... yes, I tried the training mode, and that didn't help, and yes, I downloaded the newer version, as well as running tests on different computers, even after reseting the computer. It is a COMODO issue, not my computer.
Ok, all that being said, just some things for thoughts:
1. Uninstall the "Driver Updater program", since things started after you installed it. See if that helps. Even if it does, I suggest you do at least #2, and in fact all other steps anyway.
2. Uninstall the software that your ISP may have insisted on you installing, as said, it isn't need. Don't take no as an answer from your ISP. My ISP tried the same "stuff" with me. My ISP tried that with me, and I got them, because it wasn't required by the TOS, and plus I know how to create connections without their software.
3. To be safe, backup all the files you consider critical (e.g. *.DOC, *.XLS, etc)
4. Do a deep scan with AVAST.
5. Do a scan with MALWARE blaster.
6. Do a scan with SuperAntiSpyware.
7. Do a scan with Spybot Search and Destroy.
8. Defender is just an updated version of MSE, which Microsoft has already admitted is just intended as a base line, not full protection like programs such as AVAST. Individuals using MSE/Defender is just looking for trouble. Accordingly, it was reported:
Now, Microsoft has said it sees Security Essentials as merely the first layer of protection, advising customers to use additional, third-party antivirus... Holly Stewart, senior program manager of the Microsoft Malware Protection Center, told Dennis Technology Labs that Microsoft made a decision to switch to what it calls a "baseline strategy".
Best of luck.
