I found that Google does not search when allowed to use javascript. Maybe try disabling javascript for Google. You can do that easily with the extension YesScript. It is a blacklist for javascript, and only blacklisted sites are prevented from using it.

Look, the problem persists

When I use google on search toolbar I get this

It seems It's malware, do you recomend anything free to check to system for malware? Thank you

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do not click the Reset button on the Safe mode start window or otherwise make changes.

• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

If you suspect malware the do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

I entered in safe mode and nothing. I reseted firefox and I got the same.

Every time I use google on search toolbar I get :(

I'll try all those applications

this is REALLY STRANGE

• I made a reset to firefox
• I entered in safe mode
• I disabled ALL plug-ins

and every time I go to search toolbar and google some expression I get

http://www.google.com/cse?cx=partner-pub-3540673482024757%3Ac8hkjv-9xef&q=teste&ie=utf-8&oe=utf-8&aq=t

what a puzzle!!!!

PS: The IE search toolbar is working fine

Try getting a Google search plugin from mycroft.mozdev.org, and forget about using the Google search plugin that comes with Firefox. That one is far too nosy anyway. It would seem that Google has fixed their search bug, and one can now do a search with javascript enabled again (not that I want to).

it was malware NOT DETECTED by any of those applications

It's ok now. What I did:

• remove/unistall totally firefox
• uninstall everthing regarding a malware application named something like sweet*, sweetIM, sweetpack, etc.
• unistall a malware application named tuto4PC
• reinstall firefox

then it's OK
