Yeah, it seems that was the cause.. so I'd definitely recommend removing McAfee first for everyone that has this problem, and not putting it in the first place for Lenovo

You can get another antivirus program immediately by downloading a free version. Don't be fooled; many of them are excellent. I personally ditched McAfee and downloaded Avast Free. It is lightweight on resources and works like a top (IMHO).

For some, McAfee uninstallation worked fine, but for me not.
What worked for me was uninstalling Realtek drivers and let Windows install his preferred drivers (these are also Realtek drivers, but drivers only, without the additional, completely useless software you can see usually in your tray).
And this works fine in my case, no noise in my speakers !!
PS: Now we just have to find out how to use SRS audio system (Normal, Music, Movie - which actually does great job) withous Realtek software, just where to control it ?
-All drivers given with laptop
-Windows 7 Home Premium SP1 x64

Same problem, same solution. Had some low-frequency noise when use headphones, but when I uninstalled Realtek drivers noise just gone. Still need a solution how to use SRS.
And red light from headphones plug keeps me worried that something is wrong.

I have an Ideapad U460 and I have tried updating the chipset, audio and video drivers, still have stuttering. This is a problem across the board to thousands of Lenovo IdeaPads and it should have taken cared of a long time ago with some type of update or patch, but evreytime I call Lenovo, they want to charge me for support. I'm having a bad expericence with Lenovo's customer support. If this happened to a series of Apple or Dell laptops, these companies would have taken care of it right away. I don't understand what is going on with Lenovo!
