Hijacker? (This is a tough one)

I have a D-Link wireless router rigged off of a hardwired router. It has been working just fine until someone went to "freetaxusa.com" or something like that. After that happened I can now only go to selected sites, such as yahoo; otherwise than that the browser takes me to a dell search page whenever I try to go view another page. I figured it was a browser hijacker. But the odd thing is that I had my laptop with me while I was out of town and the wireless/internet worked just fine. Even when I am at home, if I hook the computer into a hardwire, everything works just fine. I reset, reintstalled, reconfigured the router and still no luck. The rest of my computers (which are hardwired) work just fine. I have never seen this before? Is the router shot? Any suggestions?

 

Are you sure you're really connecting to your network?

 

O yes; I live out in the middle of nowhere (literally)! There is no other possible network around that I can pick up.

 

Well, since it's obviously on your computer, you need to start with malware/spyware scans. How about posting a HijackThis 1.99.1 log here.
