Spyware or Virus? Please help?

When I do a search on google or yahoo, websites will come up as normal. But, when I click on a site like wikipedia, it will redirect me to some random search engine or sites like amazon.com. What's up with that? What can I do to get rid of this? Do I have a virus? or Spyware?

I have ran avg, ad-aware, spybot, etc. it worked for a couple of hours, but now the problem is BACK. so, fraustrating. Please Help~

You have what's called a browser hijacker, where spyware forces your search to a different site, usually trying to get the person to buy something. Both Ad-Aware and SpyBot should find and remove the hijacker, so I'm thinking maybe you haven't updated them lately. You need to get the latest updates for both of them, then run them before you get back on the internet. And, it's entirely possible you are going right back to wherever you picked up this hijacker in the first place. I just looked in Wikipedia, which I use a lot, but I don't get shunted off to a different site. Update your anti-spyware and run them both again.

If your browser has been hijacked then get hold of a copy of HijackThis and run a scan.
Before you click on the search that you want. Look at where the add. you will see that your getting ready to open up another search engine. that has what your looking for on there thats why you getting redirected. Also so sometimes you wil get redirected to these cause it is in the program to redirect you there so you will use the search engine inside of what ever you opened
Go to IE menubar and Tools | Internet Options, click the Advanced tab, scroll down to Browsing and uncheck the "Enable third party extensions", close IE down and restart to see if it still acts up. Also check Tools | Manage Addons | Enable or Disable Addons. Disable any suspicious looking Addons one at a time, keep checking as you go until the problem ceases. It sould like a browser highjacker, and it could be an Addon.
It looks like a spyware. Install some good spyware program and run it. Programs like PC XP Tools, System Mechanic 7.0 Pro. Or yahoo also provide Norton, to use this you need to install Yahoo tool bar, it's free. This will solve your problem. This will scan your PC and show all adwares and spywares with it's severity. Select remove all. Hope this will help you out.
