Please help me deleting this virus or trojan or whatever.Norton detects it mostly when I restart my pc, and can't access the file. Then I close the warning windows and continue working; every now and then, the warning windows appear again! Here it is my Hijack This log:

Thanks.

Well first off, ya need to move and unzip the folder into a permenant folder (ie outside Documents and Settings). I'd say create a new Program Files folder, name it HJT or something, and unzip the HijackThis folder into the Program Files folder.
