I am shocked to find a constant music on my speaker. There were no applications on the screen. I had visited some site yesterday to download free wallpapers and screensavers. It looks there is a virus which was also downloaded. The music is totally coming from something hidden in the system. I have to turn off my speaker to shut the sound down. I tried to remove some programs which I had downloaded, but still the sound is active. How to delete that thing completely. I need more information on this virus, what it can affect more to my computer. Also please provide me a good antivirus or antispyware program that can I use to stop this. Thanks.
