My yahoo search is being redirected by google

When using my Yahoo web browser to search I end up being redirected to Google. I was reading that I might need to run another scan like malwarebytes? I am using operating system is Windows XP
Your browser is Firefox 19.0 and of course using Avast and I have CC cleaner as well.

I cannot reproduce your issue. You might want to try adwcleaner.

Go to http://www.calendarofupdates.com/updates/index.php?s=60d6a4a055b6d55831b55efabc016084&app=calendar and click on "Installers Hall of Shame (Unwanted add-on) to see why some of the junk gets installed on your computer.

What is it that I would be removing? I just searched again and I was able to stay on my Yahoo search page.

Did you run AdwCleaner as Paranoid suggested? It might find something that is doing a redirect for you. Since a search is working correctly right now for you, you could wait and see if it occurs again. We can’t tell you what to remove as there is no way for us to know what or if anything is installed on your machine that caused the redirect.

I still am being redirected to a Google search engine. Here is what I think you were asking about my computer.

have you run AdwCleaner as suggested/asked twice above?
also run a quick scan with Malwarebytes

you find them here http://forum.avast.com/index.php?topic=53253.0

post logs here

@Poon05,
Although your first post states that you are using Firefox 19, the information in your last post has Firefox 18 as the browser. Your plug-ins are not the latest, and have known vulnerabilities. Your listing seems to be edited somewhat. The redirect you are receiving indicates that your computer is infected, and running a vulnerable browser and plug-ins definitely make it easy to infect.

Unless you run the programs, you ( and we ) won’t know what the problems are. A lot of malware hides itself quite well.

This is an add on to my ORIGINAL QUESTION: 1st I did not preform this Anti-Pup/Adware; thankfully.
Now my new “real” problem. Since I ran AdwCleaner.exe. I have abosolutly no graphics of any kind on this page it is ‘snow-white’… Really. I could barley find a place to even modify; let alone reply. It nearly looks like safe-mode. Yet, the print is sorta readable. When I logged on my PC after the Cleaner.exe I did a restart and when I logged into yahoo home page I had no advertizing graphics or images. I did ‘control’ F5 and my images returned on that page. then I went to mail and saw a message and now the Avast page and the forums are not right at all. Of course; I am considering a system restore. If anyone knows how to make my graphics stay visible permanently instead of control F5 please let me know.

I ran the cleaner then I ran the clean process. I also, saved a log that says its clean I had a question now about at the end of the scan there was a message about; " You can also install Host Anti-PuP/Adware from AdwCleaner by clicking “?” and then download hosts Anti-Pup/Adware. Is this a step I need to take?

I wouldn’t install it before investigating whether it may be something you want. Can you attach the log here, so others can see it?

A scan log from MalwareBytes would be useful, too. These will give the malware removal experts something to work with.

Okay I did the control and my avast page is refreshed How to I keep my page correct with out control F5.
What have I done.

Post the log for Malwarebytes. Since you stated that AdwCleaner came up clean, it wouldn’t have removed anything nor altered any settings. Perhaps the malware is doing more damage.

Now my new "real" problem. Since I ran AdwCleaner.exe. I have abosolutly no graphics of any kind on this page it is 'snow-white'.... Really.
The AdwCleaner log you attached above say "Search" meaning it has not removed all the crap files listed in it... to do that you must run AdwCleaner and click "Delete".....

Missed the attached log. :-[
