Hi yeah will do
I will mention I've run a Windows Security offline scan last night and that too found nothing
So this file is hiding itself even from a Malwarebytes scan
Thanks will post back
 
Hi the logs will not paste due to "image type file is invalid" pop up

The logs opened in Word Pad when the scans finished
 
You can attach the files. Or upload them to a file sharing site, or post as pastebin then send the link
 
Thanks they are attached,i have never used Farbar,some of the apps/programs on that list are not on my PC anymore so there must be remnants remaining from when they were uninstalled.

  • Once the MBAM dashboard opens, click on Settings (gear icon).
  • Click on Security tab and make sure that all four Scan options are enabled.
  • Close Settings and click on the Scan button on the dashboard.
  • Once the scan is completed make sure you have it quarantine any detections it finds.
  • If no detections were found click on the Save results drop-down, then the Export to TXT button and save the file as a Text file to your desktop.
  • If there were detections then once the quarantine has completed click on the View report button, then click the Export drop-down, then the Export to TXT button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT button, and save the file as a Text file to your desktop or other location you can find and include that log on your next reply.
 
No I didn't delete firewall rules,I don't really use the firewalI I may have on the BS5 game

Where do I paste the code?
Took a while to download Farbar ,Windows Smartscreen kept popping up and stopping it downloading
 
You don’t paste anything. Copy the entire code, right click Frst run as admin and hit fix. The tool does the work. It was designed that way due to over the years people not understanding the process, it was simplified by the creator of the tool to make the helpers job easier.
 
Hi well you know what MWB found nothing but the CODE run with FRST has FIXED the Problem!!!!!!!
Thats just great
Logs attached
Thanks

It was this scheduled task that was the issue.

Task: {491E0665-D717-429E-87E8-0AC6FA1B5A2A} - System32\Tasks\MicrosoftEdgeUpdateTaskMachineId => C:\WINDOWS\system32\wscript.exe [170496 2023-10-13] (Microsoft Windows -> Microsoft Corporation) -> C:\Users\mart d\AppData\Local\Microsoft\Windows\Explorer\SQLite.flush.vbs
Click to expand...
In the FRST script I sent this file to Virus Total, Although nothing turned up on the scanners I am a bit suspicious of this file. Open the file location and rename it to .bak instead of .dll if any issues arise rename it back to .dll It is not a windows file, so it will not break the system.

C:\Users\mart d\AppData\Roaming\msregsvv.dll

Also, this part of the log is missing deleted by you by mistake? I'd like to know what the entry was....

What is this in your startup folder?

[HKU\S-1-5-21-2192984707-2358445379-1302979691-1001\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run]

"Lync"="03000000e21730c1074ad501"
There are remnants of Avira.

Bitlocker is running on your machine and known to slow a computer
As well if you do not use one drive....

Sppextcomobjhook.dll is a file that is installed on a system when the user runs software crack tools (AutoKMS) and other license activators intended to crack MS Windows and/or MS Office. Are you aware of this?

"C:\WINDOWS\System32\SppExtComObjPatcher.exe"="0"
"C:\WINDOWS\System32\SppExtComObjHook.dll"="0"
 
Hi no idea about the firewall,I have Fl20 and the game Modern warfare blocked ,FL 20 ,I don't know what the other file is? I'll see if I can find it

" Lync" never seen it dunno what it is,should I delete it?

Kms was for Office 16 but I thought id removed it as I changed over to libre office

Avira I had installed at one time because defender wouldn't run on it's own ,it would only do an on demand scan .

No I didn't know bitlocker was running,no I don't use One drive

Lot to look into there
 
Ok, we are gonna remove the remnants of Avira and Kms, then we will reset the firewall. Let’s use one more software tool to give me a look at other areas of the machine.

Download ZHP Suite to your desktop.
Right Click Run as admin.
Hit the scanner button.
Once it is complete a file name ZHPdiag.txt will be on your desktop.
Attach it.
 
Hi ZHP suite doesn't download,sits there saying getting files together for 30 mins

One problem solved now I have another Google chrome has suddenly defaulted back to default,I've lost all my bookmarks
Google tells me theres a back up in C:\users\name\appdata\local\Google\Chrome\user data\default
The folders empty
Has this anything to do with FRST ?
 
We deleted the cache data from within Chrome. This standard practice when I help users, you can see this command only deletes the cache.

CMD: del /s /q "%userprofile%\AppData\Local\Google\Chrome\User Data\Default\Cache\*.*"

This would be a first if your bookmarks were deleted. Which is not indicated in the fixlog, you can look there and see everything that was deleted from your machine via FRST

Zhp uploaded for you.

Hi yeah it's the loss of the bookmarks that's annoyed me but not only that,it's a full reset of Chrome,no browser extensions or history.
50% redone today adding bookmarks,it was just something I've not seen before.

My son came today he's a bit more PC savvy than me,so he -
Renamed the suspicious msregsvv.dll to .bak
Removed the Avira remnants
Turned off bitlocker
Removed the two Auto Kms files
He's not sure if " Lync" in Windows start up isn't something to do with MS Office

Anyway I'm going to say this is resolved,I can only thank you for your help and I've learnt along the way,some good tools that can be put to use

I will be travelling to my Daughter's today to spend Christmas 🎄 with her and my Grandson.

Hope you have a good Christmas and Happy New Year
Thank you once again 😁
