This may be related to a Conduit-powered "Community Toolbar" add-on, or similar.

Assuming it is a bad add-on, I suggest starting here:

Open the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.

You can "mop up" remaining issues with the scanning/cleaning tools suggested in this support article: Troubleshoot Firefox issues caused by malware.

Finally, start Firefox in its Safe Mode by holding down the Shift key when double-clicking the Firefox shortcut/icon. In the small dialog that should appear, choose "Start in Safe Mode"

Then open the Add-ons page using either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

(1) In the left column, click Plugins. If you find a plugin that you don't recognize or which doesn't sound essential, try setting it to "Never Activate". (The most essential Plugin is Shockwave Flash. You can use most sites without the others.)

(2) In the left column, click Extensions. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions.

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Does that clear it up?

Did everything you write, hope it will help :)

I removed 1 program I didnt know about...something from microsoft and I didnt install it (even the win update). and then there was a BS player toolbar... aslo in the extension there was that toolbar...

then I hit the "Never activate" at the Plugin: Java Deployment toolkit.

I really hope this will help... I will watch the firefox behavior, and then I will reply here if that helped :) But thank you very much, so far! ;)

Didnt see the message from ESET so far, so thank you very much jscher2000! :)
