Can't download and run malwarebytes and explorer opens windows by itself.

[youkilis]

I had malwarebytes' anti-malware on my computer before.  After a trip to myspace my computer started running very slow and explorer opens by itself, even when i am running firefox.  I have been back to the malwarebytes website and tried to download it again and i get an error message:

Unable to execute file:
c:\ProgramFiles\Malwarebytes' Anti-Malware\mbam.exe

Create Process failed; code 2
The system cannot find the file specified.

Has anybody had this problem?  And, can someone please help me out?

Thanks

The first thing I will need you to do is to go to this link and follow the directions precisely. If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line. If you can't run any step, just jump to the next one. Please let me know how you are doing or have any questions. Initially, I will need the SuperAntiSpyware, MBAM and HJT logs. Please post any logs that you can generate.

Thank you for your help.  I have tried the suggestions and tried to follow the instructions to download the c batch file.  When I try to open up my taskmanager, i get the message that it has been disabled by my administrator!  This is very aggravating and I've tried every way to find it and open it.  Any other suggestions?

download the c batch file.

I'm not sure what file you're talking about.

This is a sure sign of infection.
