Do a malware check with a few malware scan programs.
You need to use all programs because each detects different malware.
Make sure that you update each program to get the latest version of the database.

I was having a similar problem. When i did google searched it was redirecting me to ads! NO malware or antivirus programs could detect a problem! After trying many other things unsuccessfully, I disabled all my Java add-ons and uninstalled all java extensions and it was fixed! I'm not sure which one was causing it!

Here's the problem: Do a Google search, click the top URL in the results and be re-directed to an ad site or potentially harmful site that displays a warning by Web of Trust. Here's an example: Search for “ auto body parts”. Click on www.carpartswholesale.com and be redirected to www.local.com/results.asp.... Click to go back one page and re-cliclick www.carpartswholesale.com and get the correct web page. I uninstalled Java, removed WOT add-in checked all my browser settings and still was being re-directed. As a last resort, disabled Mozilla's XULRunner and no-more redirection. Anyone have any theories why / how this was happening?

If you mean an extension (Tools > Add-ons > Extensions) with the name XULRunner 1.9.1 then that extension is malware and you should get rid of it.

My browser is hijacked by this site: http://internetnews10.com/finance.aspx?dup=1&s1=151480&s2=200063.535162784&s3=&clickid=11_0_48c27139-eef9-4730-9199-226f5794ae94

How do I fix it? I'm sure its a registry entry, have run spyware, malware, adware programs but none of them pick it up. Thanks!

Did you try to search the registry for internetnews10.com with the regedit program ?

Yes, I did. I deleted 1 or 2 entries, rebooted, and it still didn't help. I totally deleted Firefox and reinstalled it. So far, it went away -- ha ha. Hopefully this may have solved the problem. Thanks so much for your reply!

I have Mozilla with ABP. My problem, ´ads served by Netbits.´ When on a page with Mozilla, ´Netbits´ blows up all over the requested page with ads... ABP blocks images - so it´s ´just´ a blanc page. I have Microsoft security essentials, firewall, Spybotts, Spywareblaster, Hijack this and Ad aware running - and I can´t get rid of the freakin´Netbits!!! I have a suspicion that Netbits comes in through temp files of Explorer. I also tried uninstalling Mozilla, removed every possible Mozilla related map before re installing a fresh version of Mozilla - Netbits ´s still all over the place... Isn´t this ´crap served by Netbits´ a form of spamming - against the laws???

I have had this problem in the past. It turned out that the virus was actually hijacking the router, not the computer. This is why the same problem reappears on other machines on the same network. Unfortunately I do not remember exactly how I solved it. I seem to remember changing the password on the router from the default to a real password.

Thanks for your reply! My router already had a "private" password so that was not the issue. Reinstalling Firefox seemed to have solve the problem!
