Weird redirect on all browsers for certain websites

[g-apple]

Hi people,

I have a very unusual problem on my mac notebook, which I have great difficulty finding a cause for.

I like to checkout the website www.guardian.co.uk on a regular basis. When I type the URL (correctly) or click a link, sometimes I'm redirected to a completely different site. The URL address bar still shows www.guardian.co.uk, but I might be looking at the www.google.ca homepage instead. A couple of other weird observations:

• Happens in both Safari and Chrome browsers
• Happens not only on www.guardian.co.uk, but also other sites as well (but more rarely).
• No obvious trigger. Site can be working one second, then I'm redirected the next second.
• May resolve itself before I reboot. Sometimes rebooting does not resolve the problem.
• My PC is on the same network. This problem does not occur ever.
• I maybe redirected to other sites other than Google.

I am completely stumped as to the cause of the problem. Anyone willing to step up to the challenge and suggest a solution?

Thanks!

You downloaded a Trojan from a sharing site or p0rn site, didn't you?

Look at the article Two new trojan horses threaten Mac software pirates (here is a geeky way of seeing if you got it to remove it). Plus run the free DNSChanger Removal Tool to see if you feel to this old trick.

Last start using OpenDNS.com and control your own DNS to stop going to known trojan hosting sites (here is an instructional video to show you how to use it).
