Most likely the flashback trojan.
Install this update > Java for Mac OS X 10.6 Update 8 if you have Mac OS X v10.6.8 or higher installed.
If that doesn't help, use the F-Securre removal tool here > Flashback Removal Tool - F-Secure Weblog : News from the Lab
When you post for help, please tell us which Mac OS X you have installed. Thank you!

The trojan you remove by updating Java.
A normal plugin you remove by it's uninstaller in the Sfari preferences or by removing it from the Library/Internetplugins folder.

You’ve been infected with the “Flashback” malware. See this Apple support document:
Back up all data, if you haven't already done so.
Select ▹ Software Update to install the latest Java update (if Java is already installed) or the Flashback malware removal tool (if Java is not installed under Lion), as well as any other available updates. Installing either of those items should clear the infection in most cases. No other action is required on your part. You must update to the latest version of Mac OS X 10.6 or 10.7 before you can install the Java update.
Change every Internet password you have, starting with banking passwords. Check all financial accounts for unauthorized transactions. Do this after you’ve secured your system, not before.

Oh my god thank you so much! It actually worked. Sorry about not specifying which Mac OS X I had, didn`t know exactly last night. I will in the future if I have more problems
