Re: Need Computer Help Fast
What have you run against it so far? At a minimum, I'd throw your antivirus program at it, along with Spybot Search & Destroy and AdAware (both have free versions).
One other possibility, and this happened to me awhile back, is that a DNS server upstream from your computer has been hacked. (DNS, for the uninitiated, means "domain name service" -- it's what translates easy-to-read things like "redszone.com" into the actual IP address of the server.) This will generally fix itself before long when the server is refreshed from a "good" source. I don't know if this is what you have, since you didn't say if anything was affected other than Google search results.
Also check your HOSTS file (on XP, it's in C:\Windows\System32\Drivers\Etc) and see if a bunch of garbage has been written to it. HOSTS is like a local DNS override and many malware programs stick stuff in there to redirect 'Net traffic.
Not all who wander are lost
