How to undo from SONAR's scan??

I got messages from NIS that sonar detected  a virus, iexplore.exe and it send it to quarantine 

 

but after a little research on the internet, ieplore.exe is the process name for the internet eplorer, so I restore it from the quarantine and now I have been infected by some virus. NIS does not detect nothing now that I excluded from future sonar scans.

 

Now how can I undo that exclusion??

 

Also that every time I turn on my computer sonar goes wild detecting and stoping viruses. like trojan.fakeav

 

and also after all this every time that i want to go to the pirate bay page the browsers (firefox, IE) closes. But the process are still intask manager. I have to end each process to open a new session.
