Help! My curser won't stop blinking?

I also keep getting ads for spyware protection in the tabs and my homepage has changed to a web page stating a security warning. I just got this computer. HP w/ Windows Vista. What to do?

I think the computer has had a spyware/ malware attack.. U can chk in the safe mode of the computer, if its the same u might have either to format the HDD or try using any malware/ spyware removal tool from the internet.
