I was having an an audio issue where one website would not play sound on the video. I already had antivirus and anti spyware, but that was not the problem. I also checked all the Add-ons for Firefox and disabled the ones I was not using, still no success. Finally, I used MsConfig to check Startup. I did not care about the applications I recognized, however, I found some I did not know why they were being in started for Windows 7. So I Google each one I did not know, and found a few that where BS, so I disabled them. This solved the problem and also helped me prevent stupid updates from going off each time I start the computer. For example I don't need the latest update for Adobe Reader or Java, my old version works fine on the few times I use the application. I think some of the crap keeps getting updated since the programmers are bored and have to justify why they are being paid to work there 8 hours a day.
