Ok … here’s what I’ve done to solve my problem.

1st I scanned with spybot but nothing regarding that lstbar thing came out from the scan.

2nd I scanned with ad aware, found 14 spyware on my system and many other negligeable objects. I deleted all of them but did’nt solved the problem.

3rd I used the db converter and that’s what did the trick for me anyway !

Thaks for the support guys !! ;D
