Random linkbucks redirect issie...please help!

This is not malware of any kind. As to what it is, see:

Eliminating browser redirects and advertisements

QHost is extremely unlikely.

Did you go through that page systematically, checking the three things that it asks you to test and then trying all the suggested fixes? What were your answers to those three questions?

What you're describing is not something that would be caused by OpenDNS. At this point, I would recommend that you make an appointment at the Genius Bar at your nearest Apple Store and take the machine for them to look at.

The problem with trying to troubleshoot this in a forum is that it doesn't seem that you have followed through on all the instructions on the link I gave you. Have you yet tried this section?

Browser plug-in issues

That's the most likely to be causing the problem.

Well, the fact that the problem stopped after you changed DNS settings suggests that was the source of the problem. Of course, it's also entirely possible that the problem is still not entirely fixed, and is being caused by an issue with the wireless router.

As to why some sites are not loading correctly, that's not a problem that would be caused by changing DNS settings. What else have you done? You mention turning on your firewall. (Note that that won't really help with this sort of issue, and is generally not necessary. See Do I need a firewall?) Did you do anything else, like installing some kind of security software?

If you have a separate wireless router and cable/DSL modem, try disconnecting the router and plugging your computer directly into the modem with the Ethernet cable that is currently connected to the router. Do web sites behave differently then?

Did you ever solve this or did you just decide to kill yourself which is my next course of action in dealing with this virus!

Ok, thanks for the reply. I had already tried that and it hasn't worked for me (on Chrome).

Thanks anyway.

THIS IS A BROWSER REDIRECTION INFECTION

No known Malware Protection/detection will help!

How it works: You pick it up on a web site and it then infects your browser.

It rapidly spreads to your wifi hub and the many other items of your network infrastructure

Finding for the hidden/embedded infection files is near impossible

REMOVAL

Close Down WiFi

Remove any RG45/CAT5 Connection

Delete Completely - all traces of: Firefox, Opera and Chrome

Reset Safari using Shift + Alt + Reset

Re-Install Firefox, Opera and Chrome

POWER DOWN every item on your network

Reboot Your Network

Reconnect WiFi and test

IFF it is normal :-)

IFF NOT: Reset & Reinstall your browser + remove and power down every item on your network

Rebuild and reboot form your first hub/router and then test. You Should be clear !!

THEN connect one item at a time testing each one for infection

I DO NOT KNOW if it infects printers + scanners et al+++ but mine are OK

First, note that this topic is almost a year old, and a lot has changed in that time with regard to advertisements and redirects.

Second:

How it works: You pick it up on a web site and it then infects your browser.

Nope. There's no known malware capable of infecting your browser simply by visiting a web site... not on a Mac, anyway. There is adware that can cause ads in your browser, if you download and install something you shouldn't. That requires manually opening some download, though.

Third:

It rapidly spreads to your wifi hub and the many other items of your network infrastructure

Nope. There's no known Mac malware capable of infecting other devices on your network. Even other Macs cannot be automatically infected by any current Mac malware. Wireless routers can be hacked remotely, of course, and a number of models are extremely vulnerable to such attacks.

As for your "removal instructions," those don't make a whole lot of sense. Most Mac adware will sit there laughing at your attempts to remove it that way, and be ready to start pestering you again as soon as you open up a browser again.
