Hello Codelas and welcome to Malwarebytes,

Continue:

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.

NOTE. It's important that both files, FRST or FRSTEnglish, and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1: This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed.

The following directories are emptied:
 
  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin


Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

Next,

Download and run the Malwarebytes Support Tool
Accept the EULA and click Advanced tab on the left (not Start Repair)
Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here

When complete:-

Open Malwarebytes, select > small cog wheel top right hand corner, that will open "settings" from there select "Security" tab.

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Clsoe out the settings window, this will take you back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Click on the Detection History tab > from main interface.
  • Then click on "History" that will open to a historical list
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

Let me see those logs in your reply...

Thank you,

Okay, so I have done everything up to the Malwarebytes Support Tool step, because it didn't work. My system didn't restart when I ran "Clean" and just asked me to install the latest version of Malwarebytes, which didn't work because of the same "Invalid Path" error. I also noticed that after running the FRST fix, none of my tabs in my browser were gone. May this be of importance? 

I attached the fixlog here.

Hiya Codelas,

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Hello Kevin! I ran the fix and it seems to have worked. I got Malwarebytes installed again, did a scan and had some detections which are now quarantined. Your help has been immense, and I am very grateful for your help. I think that I have this issue sorted now.

I have attached the fixlog, in case you need it for anything.

Once again, thank you Kevin, I wouldn't be able to do any of this without you!

- Kind regards, Codelas

Hiya Codelas,

Good to hear you system is working ok for you now, continue to finish up:

Right click on FRST here: C:\Users\maksi\Desktop\Farbar\FRST.exe and rename uninstall.exe when complete right click on uninstall.exe and select "Run as Administrator"

If you do not see the .exe appended that is because file extensions are hidden, in that case just rename FRST to uninstall

That action will remove FRST and all created files and folders...

Hiya Codelas,

Select the Windows Key and R Key together on your Keyboard, that will open the "Run" box. Type or copy/paste services.msc into the run box, then hit the enter key.

The "Services" window will open. Scroll to "Volume Shadow Copy" service. Its startup type setting should be "Manual" is that correct....

Thank you,

Kevin...

Hiya Codelas,

Download Farbar Service Scanner from here: http://www.bleepingcomputer.com/download/farbar-service-scanner/dl/62/ and run it on the computer with the issue.

Make sure the following options are checked:
 
  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center/Action Center
  • Windows Update
  • Windows Defender
 
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.

Do you have any software installed for backing up or reimaging your system...?

Open the services windows again, ensure the following services are set to "Automatic" and are currently running:

Volume Shadow Copy

Microsoft Software Shadow Copy Provider Service

Task Scheduler

When all are in Automatic reboot and check system restore again..

I don't think I have any software for backing up or reimaging my system, because I don't recall any.

Both "Volume Shadow Copy" and "Task Scheduler" are running and set to automatic, but I couldn't seem to find "Microsoft Software Shadow Copy Provider Service" anywhere in that list.

I did what you asked and "Microsoft Shadow Copy Provider" has now appeared. I started it up and set it to automatic, which seems to have done the trick, since now I can see my system restore properties now. I will continue with the guides you sent me now. Thank you very much for the help Kevin.
