Web Hijacker OSX (copy-your) taken over Safari/Firefox/IE??

[johnhobs]

Please can anyone help, trying to find posts/advice regarding this. I'm using a G5 mac with OSX, a web hijacker has taken over my browsers when i do searches on google/yahoo/msn etc! (redirects me to porn and other sites of its choice)
I have deleted all the preferences and reset safari and emptied the cache but this slowed it down for about 30mins! I then created a new account but this had no effect.

did you download and install a trojan horse disguising itself as a QuickTime codec to view porn videos by any chance? if so take a look here.

Thanks for the reply i have ordered the intego virus barrier X5 software to try and help find and delete it, i did not download any thing though that i why i am concerned.
I have read the AppleJack could be helpful - but i have never heard of it or no anyone using it... any suggestions...

DNS bug

There is a strong chance that you are being hit by the recent DNS hole; exploit code just became available in the last 24 hours, so any porn operator can take over any domain on any unpatched server in about 60 seconds. Your ISP or whoever runs the DNS server you are using failed to patch.

Apple, also, has failed to issue a patch. Give 'em a call! 1-800-MY-APPLE

It's not Apple's fault. That doesn't even make sense.

In the meanwhile, use OpenDNS as a substitute for your ISP's DNS servers.
