ono out of two things. I would suggest you delete your cache. If you are using internet explorer go to tools, internet options and delete files and cookies. If that don't work you may have some spyware on your computer.
You need a removal tool like spybot, which is free the last time i checked.
- Don't let negative things break you, instead let it be your strength, your reason for growth. Life is for living and I won't spend my life feeling cheated and downtrodden.
