More details required!
At a guess, you're saying that you get this error message, in Internet Explorer 6 (maybe 7 ?) on a PC running Windows XP with service pack 2......?
For a quick workaround/ solution, grab a copy of firefox from
www.getfirefox.com and that should let you browse the interwebs without any hassle, but if you want to fix your actual problem, more details are needed.
