Serious Computer virus/trojans/mal/spyware problem

Ok, so basically my dad must have clicked on something or downloaded something onto my computer, and now its really slow and several porn windows popups every minute. I did everything on the "READ AND RUN ME FIRST before asking for support" page and basically i have two logs for you to look at and check if possible, one is the bdscan.txt and the other is the log from hijackthis.exe/analyse.exe. Thanks again for all your help...



Symptoms:

-porn popups (rapid)

-Little white question mark with teal outline, switching to a red circle with line through it in my lower right toolbar. If i click on it it says:

"your computer is infected! Critical systme error! system detected virus activities they may cauase critical system failure. please, use antimalware software to clean and protect your system from parasite programs. Click here to get all available software."

-yellow flashin triangle with "!" in it, it pops up in a window every now and then and says, "security alert, blah blah blah (how people can steal your creditcard info and such)"

-popcorn license manager in the add/remove porgrams in control panel, not sure what it is, but i think its bad because it keeps popping up saying that my three day trial has expired.

-Also, I know that I have Intcodec on my computer, in some of the programs that i ran to scan my computer they labeled it as multiple viruses.


That about covers the symptoms of my computer, thank your very very much for looking at this and possibly helping I need all the help i can get, i need this computer for this up coming school year!

-Andrew

edit: if there is any more information that you need to help diagnose the problem then please tell me so i can get on it asap.

Once you get to the last one click YES and it will reboot. Note many of the file list below may not exist but we need to check for them anyway.

If Killbox does not reboot or you get a Pending Operations type error message just reboot your PC yourself.

Now boot into SAFE MODE

Open ExplorerXP navigate to and DELETE the following: (Some of these may have already been deleted by Pocket Killbox)

Now run CCleaner. If you have Windows XP delete the contents of C:\WINDOWS\Prefetch.

Then, as an added precaution, Go to Start -> Run and type: cleanmgr and then click OK. Make sure the boxes for these are checked:
