wp-malwatch generating 404 within wordpress

Hi,

When I run Wp-Malwatch, I get a 404 error within WordPress, not as a separate page. What’s really spooky is that the 404 generated is for another site and not my 404. Dreamhost has been zero help with this. After suggesting a couple of things that didn’t make sense to me and didn’t work, they blew me off and tried to sell me on moving to a private server. Does anyone have any idea on why, how this could be happening???

thanks,

Nancy
