Pre Boot scan scheduled after next boot

After Scanning D: drive [20%]

DELETE: Error 0xc0000035  {Object name already exists}

Keep pressing: 6 Delete All

Error comes back every time

Keep key 6 down for 5 minutes keeps on scrolling Error and menu

Seems to never end.

I'm afraid that's quite a generic error so I'm unable to say why it happened.
Could you please attach the following two files:
C:\ProgramData\AVAST Software\Avast\log\aswBoot.log
C:\ProgramData\AVAST Software\Avast\report\aswBoot.txt

I'm not saying they will necessarily show the cause, but they do contain some more detail, so they can help.
Thanks.

It's a hidden folder. Make sure you have the correct folder settings.

I am no expert in this! But I think nothing unusual detected?

I concur with that, the system looks clean

Is it a backup package that is being detected ?

My system has problem with Graphical Driver (NVIDIA) Windows 8 says, sometimes mouse moves funny than system freezes, hard reboot required. Also MSN Messenger keeps asking to upgrade to Skype, which I have done already, MSN not deinstalled some how by update upgrade to Skype. Lots of spontaneous reboots too!

It may well be worth updating to 8.1 as that does clear a few graphic type errors

What do you mean? I have no third party backup system by the way

As it was on a separate partition I was wondering whether they were the original images or compressed back up images

It are indeed uncompressed (former Windows 8.1 from FileHistory Control Panel) Backup System Images on external 1 Tb HD, that was still attached during scan, usually I disconnect and unplug power to save HD

It may be worth checking one of the image files at virus total as a double check

Go to Virustotal
Click Choose File and navigate to an image file on the external HDD and select it
Then press scan it



Once it has completed could you copy the link and post it here

I will do that in a couple of weeks, I have perhaps business with those files, who are from two different W 8.1 computers by the way, cannot give them out of my hands yet

Today first time that ext. HD was attached to this problem W 8 build by the way, cannot be the problem
