This is the link I encounter. I only extract a half part of the link. It's really long. http://srv123.com/ads-clicktrack/click/newjump1.do?affiliate=64485&subid=024&terms=austin%20texas%20youtube.com%20video%20sharing%20camera%20phone%20 Why did I have this disturbing link? How can I fix this issue?
Sounds like you have some spam-ware infecting your browser.
Run Spybot search and destroy and Hi-jack this to remove them.
Also uninstall any random software from your browser and computer.
