In need of direction

Hello,

I am very . I beleive I was hijacked a few weeks ago. My homepage and search tool were automatically changed. Ever since, MOST links I follow, I receive a 403 Forbidden error and flash does not work properly.
I have installed ad-aware 6.0 and spybot and ran them, they found some stuff but no viruses, trojans or worms. I have tried on-line scanners and hijack this but cannot download them or am forbidden from getting to the page. I am on the verge of reformatting my hard drive.... I am running windows 2k, EZ trust firewall and EZ trust antivirus (no viruses found)

What do I do now?

Thanks for any help on this.

 

d/l hijack on another computer and save to floppy,then run it on your comp.
