I’m a CQ40-328TU & Vista SP2 user. Last August ... when I trying to install 1 (One) file, my CQ40 alert me that the software is dangerous … and after that I unable to rename or moved all folder … not file.
Once it was deleted, and moved to Recycle Bin, the folder is unable to be restore.
All actions are terminated immediately without any warning.

I’ve tried to open Task Manager & Regedit … it was OK … and found NO process which used HUGE resource. So I checked my Vista UAC ... and the UAC was informed to be OFF.

So … I’ve tried to goggling my problem and found:
[Only registered and activated users can see links. ]
[Only registered and activated users can see links. ]
… and Download the file > placed on the desktop, right click, Extract Here > right click, Merge > Restart
but nothing changed

Please let me know what is that? Is it a virus? IF YES, please tell me how to solved it?

The attached file is the loq from HiJackThis which done on September 20, 2010
Please help me to analyst it.
Thank you
