Is it just me or are there new ad's everywhere?

I'm not sure if you fall into this category, but...

This procedure has succeeded with others here who've complained of background noises/voices/music.

Try this:

Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter. You will now see some drivers being loaded. There will be a pause at some point. This usually lasts for no more than 30 seconds.

Now open your browser and download TDSSKiller.exe from Kaspersky Lab. It's tiny, and takes just a minute to run. It hunts down and kills a specific family of rootkits.

Regardless of the results, download and run Dr. Web CureIt! (still in Safe Mode):

Now download the free version of Malwarebytes’ Anti-Malware (MBAM). Install it, get updates and run a full scan:

You should now delete TDSSKiller.exe and Dr. Web CureIt!, as updated versions are often made available. MBAM can be easily uninstalled, but it may prove to be beneficial in the future.

Hope this helps.
