Go and download Microsoft Antispyware, then run it, and it should be able to remove the offending helper objects from your browser.
Antispyware will also protect you (or at least warn you and ask permission) the next time an errant web site tries to do this again.
And for goodness sake, turn OFF all Java, and ActiveX controls, or at least set them to "prompt" and then only say YES to sites you KNOW you want to run things on.
Do these things infect all types of computers (PC and Mac)? I went to that site as well and my browsers have been acting up.
BTTT!!!!
Can you tell give me any more information about "browser hijacking"?
I'm learning a lot here today. Appreciate it.
