I dont think this is going to be malware related but, just to be sure,

Let's download ComboFix.exe. This will give me a better view to the files running, those that are hidden, and also those in the registry..Please download from one of these webpages .

http://download.bleepingcomputer.com/sUBs/ComboFix.exe
http://www.forospyware.com/sUBs/ComboFix.exe
http://subs.geekstogo.com/ComboFix.exe


* IMPORTANT !!! Save ComboFix.exe to your Desktop


Disable your AntiVirus and AntiSpyware applications, usually via a right-click on the System Tray icon. They may otherwise interfere with our tools.

Double-click on ComboFix.exe & follow the prompts.

As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.Recovery Console can be installed from your disc if you have Vista if you wish.

Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.





Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:





Click on Yes to continue scanning for malware.

When finished, it shall produce a log for you. Please include the ComboFix.txt in your reply.

thank you so much for helping me! before i include the log, i feel i have to let you know that the following things happened after i installed the combofix:
not only i get the "IE script error", but i get another pop-up now as well, asking me whether i'm sure i want to close... quick assistant.
a third pop-up appeared saying that i have a parasite, and a file is trying to attach to combofix. this is the file:
C/ProgramFiles/CommonFiles/Logitech/LVMVFM/LUPrcInj.dll
finally, although i had deactivated my avg antivirus as you instructed me, i received another BSoD!!! (i include the log)
so... the combofix log follows right after this

Ah, that should explain the problem.
Ok, you should be able to get to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl
when you've got to that folder, go to edit, new key. A new folder will be made, rename it to
FEATURE_BLOCK_LMZ_SCR IPT

Now move on to step 3.

oh, something else too: combofix never prompted me to install a Windows Recovery Console...

i just did. should i restart my computer now or everything should be ok?

another question: windows recovery console is something i SHOULD install, and if it is necessary for my pc's well-being, how can i do it?
Apart from all these, i am really gratefull to all of you guys for taking the time to help me! thank you so much!
