My computer suddenly plays random sounds

[Help Art]

Hi guys!

I am really a computer noob, and I really need help to figure out the problem I have with my laptop.
Beginning yesterday, my computer suddenly plays random sounds that I think come up from some sort of advertisement or radio dialogues, some last for a few second, some lasts for about 3 minutes or so.
And I am using the Logitech MX Revolution Mouse, and notice my mouse automatically go from click-to-click scroll mode to free spin scroll mode, which I think indicating that my laptop opened a few invisible advertisements.
I try to run spyware and antivirus using PC Tools Spyware Doctor + Antivirus, and everytime I cleaned a few Adware.Advertising and Application.TrackingCookies, when I run yet another scan a few minutes after, I find the same infections again and again.

Can somebody tell me what happened and how I can solve this problem?
Thank you!
