Ok ive recently noticed yahoo search engine, clicking on any of the results will redirect me everywhere.
Now im noticing pop up ads. When I use Google, it doesnt do that at all. Ive ran MacScan, Mcaffe. Nothing picks up? Anyone could help? Has anyone gotten into this problem?

Macbook Air, Mac OS X (10.5.5)

    Yahoo is a known source of malware, for the most part directed at Windows users and which cannot affect a Mac. However Trojans are another matter, one example of which is the one called 'DNSChanger' or 'OSZ.RSPlug', which can alter the DNS settings of your network connection. This particular Trojan can be inadvertently installed if you have come across certain Quicktime movies where got a window stating that you have to download and install a particular codec in order to see the video.

    If you have agreed to that installation, your system can be infected and your DNS settings altered, which results in your system using the wrong DNS servers, which can slow web surfing to a crawl.

    This can be fixed by downloading and running a freeware utility called DNSChanger Removal Tool which you can download from here:


    Once you have run that utility you have to re-boot your Mac, then reset Safari, and re-enter your DNS settings in System Preferences/Network.

    Then try this:

    Delete all cookies to do with Yahoo, as well as any Yahoo-related bookmarks.

    Restart Safari, and type in the URL for Yahoo, to create a new cookie (if you want to), and a new bookmark.

    I'm having the exact same problem. Any search results in Yahoo, and they redirect to "results.yahoo.com" and then to a random site, slightly relating to my original search.

    I ran the DNSChangerRemovalTool as well as MacScan, with no hits.

    For a few days, it would stop when I went into System Preferences - Network - Advanced - TCP/IP - Renew DNCP Lease. One time it even kicked me off the internet until I did that. But now it doesn't do anything.

    This doesn't happen with Google search results. And this happens on both Safari and Firefox.

    I deleted all cookies as well.

    Also have the same problem, except that all my google searches got redirected.
    NOW, my browser can't even connect to google, saying that cookies are stopping it from connecting, but either way, does anyone know how to fix this?
