NIS 2011 Kills Tweetdeck

Guys i opened tweetdeck tonight and was suprised to have norton sonar catch it and we quarantine tweetdeck.exe. I'm sure most of you know what tweetdeck is and i was very very suprised to see norton do this. Now its in my quarantine section and i tried to see if there was a way to have norton unquaratine the file but i don't see a way. This is the first time norton has every quaratined a legitimate file for me:

 

 

Category: Quarantine
Date & Time,Risk,Activity,Status,Recommended Action,Path - Filename
3/18/2011 10:57 PM,High,tweetdeck.exe (tweetdeck.exe) detected by SONAR,Quarantined,Resolved - No Action Required,d:\program files (x86)\tweetdeck\tweetdeck.exe

I guess the first thing is is how do i get it out of the quaratine...the second is that norton shouldn't have detected it as milcious. It should have been able to determine through file insight that it was ok.

 

Any help would be appreciated.
