Re: Unable to use Windows after updating the DAT file

Hi there! I took your email address out of the post (don't want anyone to spam you), and I will give your email address to customer service to answer those questions for you.

In the meantime, are you still down? I'd like to help!

Re: Unable to use Windows after updating the DAT file

Many thanks for replying and removing my email etc.

I don't know how many others in the UK or elsewhere,  didn't see the connection between update DATs and the failure.  I closed down for the night after the update and rebooted in the morning.

As I've said I took my machine to PCworld for repair,  since I couldnt get into restore etc and like most others don't have an XP disc, didn't see anyway I could repair and didn't want to do a manufacturers reinstall.

But one lasting issue,  that the technical staff had to deal with was the copy and paste.  If this remains an issue for anyone, when the IE failed\internet etc, it unchecked in security the copy and paste option,  which then for some reason caused problems throughout windows.

I backup, I keep a good antivirus, I update windows.  But without a XP disc,  risks were to high to have lost come of my recent files, photos of the grand children, from this month.

I was only able to track down information of the night and here when I could access on someone elses computer,  which is where I am now.

So, we need to spare a thought for those out there who have no knowledge of what is now happening to their machine and the precious data they could have lost. PCworld, were about to reformat mine, although the techie was spending extra time to retrieve the one last important (not backed up) file,  photo by photo, since there was no other way.  What a guy .  But we got there in the end and it's repaired - but, as I previously posted it cost £70,  others are paying even more.

So let us look out for our friends.  Regards to everyone and hope you all get sorted.  I get my baby opppps computer back in the morning.

Re: Unable to use Windows after updating the DAT file

I'm so very sorry you lost data! I'll glad the tech you worked with was so considerate!!

I hear what you're saying. I've been working (for about an hour now) on getting some simpler, easier to follow steps out just for my home users. We're also still testing some other repair options, so hopefully very soon we'll have this taken care of.

In the meantime, thank you for your post and the good information!

Re: Unable to use Windows after updating the DAT file

Many thanks

A lot of people are going to be caught out on this.  It's very difficult when confronted with the problem to see the connection  between DAT updates and a failing, flaky OS,  getting worse before your eyes.  No internet connection, no restore..... could it get worse.

Sadly, this is going to cost a lot of people heartache, not just out of pocket.  Perhaps by tomorrow most of the techie repairs will be up to speed, but I I was seconds away from a F5 reformat,   for what was being identified as a VUNDO trojan.

Good luck everyone

Re: Unable to use Windows after updating the DAT file

Hello Somer

Presuming you're still awake (sleep being for the weak...)

I won't bore you with the details of my 5958 troubles except to say that since I have NO - Internet acces - Restore - Copy/paste - Drag/drop AND - No CD drive (it's a netbook) or copy of the relevant XP (OEM preinstalled,) I'm in a bit of a fix!

What I'll need from you (I think) is an exe file that I can download to a USB key and then (hopefully) have it unpack and install itself and FIX the thing.

As to how you can compensate us all - I'll leave that to you...

In the meantime, have fun and don't work too hard!

Re: Unable to use Windows after updating the DAT file

Hey Mick!

Try this for me:

  1. Start your computer in Safe Mode.
    To do this, press F8 during Windows startup. When you see the options, select Safe Mode.
  2. Open My Computer.
  3. Navigate to C:\Program Files\McAfee\VirusScan.
  4. Delete the DAT folder.
  5. Press the CTRL, SHIFT, and ESC keys at the same time to open Task Manager.
  6. Click File, New Task (Run...).
  7. Type cmd and press ENTER.
  8. In the command prompt window type the following command and then press ENTER:
    NOTE: Type the command exactly, including the spaces.

    copy %systemroot%\system32\dllcache\svchost.exe %systemroot%\system32\

  9. After the file has been copied, restart your computer.
  10. After the computer has restarted, right-click the M icon and manually check for an update to get the new DAT files.

Re: Unable to use Windows after updating the DAT file

Hello Somer.

I've tried this fromTS100969 but no good.

Could you just point out to me where the spaces are...?

I see one after copy and one after exe?

Re: Unable to use Windows after updating the DAT file

That's right:

copy  SPACE %systemroot%\system32\dllcache\svchost.exe  SPACE %systemroot%\system32\ ENTER

If you're getting a file not found error, try this one:

copy  SPACE C:\WINDOWS\ServicePackFiles\i386\svchost.exe  SPACE %systemroot%\system32\ ENTER

Re: Unable to use Windows after updating the DAT file

I get the same problem as mick. The file was not be found in dllcache but tried to retrieve it from the OS disc but the only file we found was a file namned svchost.ex_  We tried to rename it but do not know if that is the way to do it? Where can we get a proper svchost since we didn't have it on our computer? Pls note that all the services (workstation, computer browser, print spooler) have startup method automatic but is not running and cannot be started manually. File not found.

Re: Unable to use Windows after updating the DAT file

If you have the windows CD, run a system file checking scan:

  1. Click Start.
  2. Click Run.
  3. Type sfc /scannow, and click OK.

System File Checker will scan the system and attempt to repair the missing file. If System File Checker is unable to locate a replacement file, it may prompt  you to insert your Windows XP disk. Insert the disk to complete the repair process.
