What you are seeing is at Windows, if you hit F8 before Windows starts to load you get those options. 
The F8 I'm referring to is initially at power on.  When the PC is powered on it does a "POST" (Power On Self Test) and you should get a Dell splash screen.  Its at that point that you press F8.
 
 

If you have data on the hard drive(s) in that computer, you might consider pulling the drives out and putting them into a different computer, then scrubbing the drives using MalwareBytes and a full virus software scan, followed by backing up any critical data files (like existing Sonar projects or documents).  Because the 2nd computer would be reading those drives as data only, and not trying to boot from them, you can use the 2nd computer's antivirus software and a free version of MalwareBytes (or the trial of the fancier one) to clean off the data files from those drives.  Just make sure you scrub them prior to backing up their data contents, and skip doing any other access of any system files/folders from those drives - you just want to retain any data from them.
 
I hope that helps you preserve things you might not easily replace.  If your problematic computer stored documents and projects and such on a different hard drive then its C: drive, then you can reload Windows on the bad C: without affecting any other drives present in that computer, though I would still do a thorough/full antivirus scan and run MalwareBytes on those drives in any case.

Thanks Gang...

I managed the first step. Using my win7 disk from my main DAW (OEM) I ran repair. Startup repair didn't help, but system restore did...

Now I'm back to trying to remove the ads by name criminal...

So far unsuccessful, but I just got some more info to try tomorrow...

I've been afraid to install MalwareBytes thinking it will add more malware... Hard to know which programs are both legit and a clean download/install... If this next attempt doesn't work I will try that route...

In trying to clean Firefox, after uninstalling it and erasing its folders everywhere, I could not delete the fokder from appdata/roaming. The warning keeps telling me I need permission from me? I'm already logged in as administrator and there doesn't appear to be a way to do this as you can "run as administrator" for a program... What do I need to do to deal with this?

Currently the machine only has the single drive and Sonar is installed but not yet really setup or used... I will do these things once I get it cleaned up enough...

McAfee reports the drive clean and I've manually removed numerous softwares and installers... I'm getting close...

So I thank you all for the good info and directions... I will post more after my next bout with it tomorrow...

Thanks fireberd, TerraSin, slartabartfast, and robert for all helping me with this little project! I hope I can return the kindness when you're in need!

OK, so if you got back into Windows, make a restore disk and a backup disk before this happens again.

Thanks...

I did a very full backup today prior to any further actions... It's not really good as it's got the adware junk, but everything else is fine...
Tomorrow I will create a dell restore disk...

You'd never know that I work on many dell machines and I used to be a PC tech for EDS who at that time did all the Dell repairs for Northern California! ;-)

Please DON'T be afraid to run Malwarebytes. It is probably the best Malware scanner there is. You should run after any standard virus scan. It's essential.l!

If you have difficulties removing malware and viruses try running the utils in safe mode after you've first run them in normal windows..
