So, I recently fought a battle with some pretty tough viruses/malware. I got them all, which is great. But somewhere along the line, something got messed up. Now there is no sound in my internet browser, no matter which browser I use. I have windows XP and the internet itself works fine. Additionally, the volume icon has disappeared from the system tray and the computer volume no longer responds to me pushing the volume buttons on the actual keyboard. If anyone thinks they can help, let me know.
