Hello! My computer is infected with a very smart spyware, and i can't get rid of it. I read much about it, even the topic http://www.daniweb.com/techtalkforums/thread16204.html which is completely about this hotoffer.info... But i have a problem, the file they are referring to (C:/windows/system32/systr.dll) does not exist on my computer, so i dont know what to do now... I have a Hijackthis log:

tnx a lot, Mister Marvioso

Hi Mister_Marvioso, welcome to DaniWeb

Get the Pocket Killbox from here:
http://bleepingcomputer.com/files/spyware/KillBox.zip

Unzip the file to your desktop.

Go offline until this is completed (you may wish to print these instructions).

Boot into Safe Mode and do a search for these files and delete any instances found (be sure your system is set to Show hidden files and folders):

param32.dll
guninst.exe
popup_bl.dll
systr.dll
svrhost.exe

If any could not be deleted, (most likely param32.dll), run Pocket Killbox and paste the full file path of file in the box and click on Delete on Reboot. Click on the button with the red circle and an X in the middle; you will get a message saying File will be deleted on next reboot, Process and Reboot now?, Click Yes to reboot. (Note: the 'file path' will be something like C:\WINDOWS\System32\param32.dll)

Reboot normally and delete any unwanted icons from your desktop.

Empty your Recycle Bin.

Before fixing anything with HijackThis, you need to move it from the Temp folder it is in now into it's own, permanent, folder; like c:\HJT\hijackthis.exe.

After you've moved hijackthis, close any open browser windows, scan with HJT, and post a new log please.

By the way, in your next post can you tell us if you know what these (bolded) entries are?
