Word 2007 crashes shortly after opening a Word file (Post-malware infection)

In this thread: http://www.bleepingcomputer.com/forums/topic458779.html/page__st__15__gopid__2770461#entry2770461
I asked for help with problems that were occurring after Avast found a malware infection on my computer.

Right now what is happening:

When I open a Word file, it freezes & then crashes (details below) often w/in 10-20 minutes of opening the file, but occasionally it has been longer (it went 3 hours once). Sometimes it happens when I am doing resource intensive things with an image dense document, other times it has happened when I have left the computer and the document is just sitting here open.

This often coincides with an extreme slowdown of everything running on the computer (though each has occurred separately).

I went through the suggestions for dealing with slow computers frex:

I have:

- cleaned computer
- went through Firefox troubleshooting checklist
- cleaned hard drive (used CCleaner)
- ran SFC
- ran Chkdsk
- checked for problem entries in Device Manager
- checked DMA status (already enabled)
- defraged system
- defraged page files
- checked for unnecessary running services
- verified Windows indexing system was disabled
- Disabled visual effects
- disabled Ctfmon.exe
- disabled mdm.exe
- ran TFC
- tried doing a clean boot
- a number of things I believe were directly related to the malware checking/repairing (OTL, ESET, aswMBR, DDS,
- uninstalled & reinstalled Word multiple times (including 2 fresh downloads - legal, I hasten to add! I bought online & added a digital backup service to my purchase, so I can redownload from a specific to me link as needed.)
- checked for unnecessary applications loading when Windows boots [but some of these have just reappeared - I'll go back and try again]

After I sent in (another!) error message, Microsoft Office popped up a diagnostic, which did not turn up anything.

The error report I get when Word crashes is long. Here's a summary [if there is any part of it that would be particularly illuminating, let me know & I can type that up - I can't copy & paste from the thing-y, and I do not want to type the whole thing up if I don't have to!]:

Any suggestions as to how to go about diagnosing (and repairing!) this would be very much appreciated!

Thank you!

Are you using Avast Antivirus?

Are you using Avast Antivirus?

Roger

Yes.

I'm sorry I should have included that clearly!

6/17 an Avast "quick scan" identified Win32:Malware-gen in a file. We chose "delete". No difference was noticed in the computer's functioning.


Except: Word stopped working. When I open a Word file, the Word screen opens, but no content & it is listed as "not responding".


An Avast "boot scan" on 6/18 turned up nothing

An Avast "boot scan" that covered more (it ran all night) identified a Win32: Malware-gen in the same file. We chose "move to chest" and the crashing stopped.

It was after that that I first tried uninstalling and reinstalling Word (Home & Student 2007).

The various scans/repairs I was instructed to do in my malware help request posting made a definite difference & I was able to reinstall Word and have Word docs open normally, let me edit (if they stayed open long enough), etc.

This is why I was asking.
snxkh from your first post. Could have been Avast or Malware.

Since it isn't Malware can you turn off the Antivirus as regards Word or office. I have seen Antivirus cause problems that way.

How do I do that?

Thank you so much!!!! I am very excited that I might finally be able to finish the project I was working on when this all began!

Eliana

I managed to type since it is Malware where I meant isn't Malware, Hopefully you got my meaning.

DO not disable the Antivirus and leave it that way just do it as a test. I wish you luck
