W7 x64 several system files missing

Hello thar!

Since i installed windows 7 about 4 months ago I have had no problems at all,
However since 2 days ago I've started getting several blue screens, so i gave CCleaner and did the HJT fix.
Now the BSOD seems to have stopped, however I can no longer play Warcraft 3:Frozen Throne without getting fatal errors every time, sometimes it takes 20 minutes, sometimes i get them whilst still in the menu.
I have reinstalled the game 2 times, once with the cd's and once with the blizzard installer and that didn't fix anything at all.

So i did the HJT scan again and found that there's several missing files from the system32 folder, this surely cannot be a good thing and im assuming this is what's causing the fatal errors and also caused the blue screens.

I've been looking around interwebs for any way to replace or repair these files, but I haven't had any success so far.

I would be very greatful for any help on this matter, mainly because i would like to avoid doing a clean install.

Below follows the Hijack file as well as my system/hardware information:

Sorry if this is posted in the wrong part of the forum, wasn't sure wich one i should post it in.


Cheers

 

I don't see any anti virus in your HJ log.

And some of your 023 services look suspicious.

And, you are having erratic performance issues.

I'd recommend you start here;
Read and Run Me First

Run the steps, start a thread there if you find anything or run into any blocks on the procedures.

Then see;
How to protect yourself from malware
:wave:wave

 

Sorry i forgot to mention that I've already done the Malware removal guide,
I had spybot and ad-aware installed, but neither of the found anything, neither did malwarebyte's anti-malware.

 

What regular anti-virus program do you have installed? I.E. Avast, Avira, McAfee etc?

What was the result of the last scan with this program?

 

That would be ad-aware, last scan was yesterday, it found nothing

 

You need to install and run an anti-virus as soon as possible. Not having and using an antivirus product is very risky.

I would recommend Avira. It is free and I have had very good results with it.

http://www.free-av.com

Other people on here may recommend Avast, ClamWin, AVG, etc. These are also good products.

 

well, this is what happend when i tried to install avira -.-

I used the sfc /scannow as well, I've attached the log.

 

Have you tried this more than once?

If so I would suspect a memory error and I suggest you burn memtest86+ to a CD and run it overnight.
