Bad Request (Invalid Header Name)

[Sniper1515]

I keep getting this message every time I try to go to web pages in my bookmarks and when I type in the URL manually. I know it is not my ISP because my other computer works just fine, and it doesnt do it with cainslair. Has anybody heard of this problem? is it a virus or just something I may have done?
I am using XP Pro 64

HELP!!!!

Time to look for adware and spyware. Also do you have any "Toolbars" installed?

hijackthis!

i think mapes is right. try unplugging the pc from the net. if it does something similiar, its probably "forwarding" your request for a site though another site.

And remember to run you spyware checks in safe mode with system restore disabled.
