All 64 bit Apps work but no 32 bit apps work

January 23, 2012 at 11:12:43
Specs: win7, p4 3.1ghz
I have windows 7 64 bit os with Amd Phenom II x4 840 processor

Yesterday While watching a movie on my computer it crashed. After it restarted I wasn't able to open any kind of applications such as Internet explorer,firefox, google earth, ad-aware. After searching further into it I discovered I could open all 64 bit applications and no 32 bit.

For example on Internet explorer I can open the 64 bit version ( inside program files) but not the 32 bit version (inside x86 program files)

When I open the program - I see inside the taskmanager the .exe file for about 1 second and then it closes- at the same time I see a .exe file called WerFault.exe *32 for 1 second also. There isn't any other abnormal .exe files running in the task manager.

The werfault program doesn't give too much discription online and claims it's not a threat

I opened my recovery manager and recovered to the date of my last system back up over 1 week ago. It's still doing the same thing

Since it's still doing this after a revert- I'm suspicious it's a hardware problem-I'm unable to open my device manager either So I don't know if there is any kind of hardware issues.

Any ideas?

Additonally-
I'm occasically seeing in the task manager

Scvhost.exe *32 running at 100k memory- Although I know scvhost is normal- this one is abnormal from my normal processes. With it Open- and I attempt to run a program- the .exe file displays for one second without the werfault.exe file.

When I end the task of the scvhost file and attempt to open a file- The werfault program displays.

I am suspecting you have an infection that is masquerading (on Task Manager) as something normal.
Run msconfig, go to Start tab and uncheck everything except things that are clearly Microsoft and your antivirus program, Apply and restart the machine into Safe Mode with Networking.
In safe mode install and run Malwarebytes and remove anything it finds.
Restart normal and see of that helps.

If you want to really see what all of the schost.exe 's are then download and install Process Explorer from Microsoft since it will show you details that Task Manager does not and you can even stop processes from it.

Restore point.
Boot to w7 dvd and use repair.

My msconfig actually already had everything unchecked.

My services under admin tools was already altered to the extent of what I felt needs to run/not run . There are no unique services that I'm unaware of running.

I went into safemode with the same exact outcome. I can't run any 32 bit applications but all 64 bit applications work just fine.

As stated in the first post- I reverted to a restore point of last week. At that time I did a full scan of Malwarebytes, Spybot search and destroy, Ad-aware, Hijackthis, defrag with my own clean up. I also fully backed up my hard drive ( Along with a restore point)

At the moment I can't run any of these repair tools as they are in 32 bit form.

I was able to get to my device manager- it claims all 4 cores to the processor are working fine and also that there are no hardware connection issues.

I can use the backup- but I have a feeling it's going to do the same thing.

It is normal and necessary that there be several instances of svchost.exe running. But carefully note the spelling. If you have any instances of scvhost.exe, as your post mentions, these will almost certainly be malware. The similarity in spelling is no accident but designed to deceive.

If you do your repair or restore from a Windows 7 install DVD or from a Windows 7 Repair Disk you would be booted to the disk and not to the installed operating system and every feature would work so you should be able to fix your system files. You can make a Windows 7 repair disk from any other 64bit Windows 7 machine and it will work on your machine if you need it (a very good tool to have).
If this does not work, back up and reload your system entirely.

Okay.

So I discovered a bad svchost.exe in C:/windows with the created file of yesterday ( Svchost original location is in /windows/system32)

In the discription of the file it states it's previous name is winrscmde.exe which online says this is malware.

Unfortunately I'm having problems getting rid of it- If I delete it , it reappears after a few seconds. In safe mode I'm still unable to run anykind of malware programs or anything for that matter - even Process Explorer doesn't work.

I did a regedit scan of winrscmde and it came up with nothing.

On another machine make one or both of these rescue disks, they can scan your Windows partitions from outside of Windows and remove the problem:

http://www.avg.com/us-en/avg-rescue-cd
http://support.kaspersky.com/viruse...

Note, after you remove the problem, if windows runs well, delete all restore points and create a new restore point to help prevent it from reinfecting. If it will not boot try a start up repair.

If this fails, use a Live Linux like Puppy Linux to save your files and then reinstall Windows, your programs and your files.
