Please download the FRST 32 bit or FRST 64bit version to suit your operating system. It is important FRST is downloaded to your desktop.
If you are unsure if your operating system is 32 or 64 Bit please go HERE.
Once downloaded right click the FRST desktop icon and select "Run as administrator" from the menu"

If you receive any security warnings, or the User Account Control warning opens at any time whilst using FRST you can safely allow FRST to proceed.
FRST will open with two dialogue boxes, accept the disclaimer.

  1. Accept the default whitelist options,
  2. If the additions.txt options box is not checked please select it.
  3. Then select Scan

Frst will take a few minutes to scan your computer, and when finished will produce two log files on your desktop, FRST.txt, and Addition.txt. They will display immediately on the desktop, but can be reopened later as a notepad file.

Adware Cleaner

  • Download AdwCleaner and save it to your Desktop
  • Right-click on AdwCleaner.exeand select
    Spcusrh.png

    Run as Administrator
  • Accept the EULA (I accept), then click on Scan Now
  • Let the scan complete
  • Once the scan completes, make sure that every item listed in the different tabs is checked and click on the Clean & Repair button
  • Subsequently you may be asked to Run Basic Repair. This is optional. I would suggest holding off on this for now.
  • Once the cleaning process is complete, AdwCleaner will ask you to restart your computer
  • Close all other open windows and allow it to restart
  • After the restart, Notepad will open with the AdwCleaner cleaning log
  • Please Attach the contents of that log into your next reply to me



FRST Fix.

Download attached fixlist.txt file and save it to the Desktop. NOTE. It's important that both files, FRST/FRST64 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 that particular machine. Running this on another machine may cause damage to your operating system Run FRST/FRST64 and press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run. When finished FRST will generate a log on the Desktop (Fixlog.txt). Please post it to your reply.

I need the Adware cleaner log, and tell me how things are running, what issue(s) remain.
 
still cannot change permissions, or ownership, or microsoft defender registry, all permissions are greyed out. cannot close antimalware service executable. although memory usage has decreased from an average of 220 to 190mbs
 
Ok.

Let's do this....

Step1:

ZHP cleaner Scan.


Please download Zhp Cleaner to your desktop. Right Click the icon and select run as administrator.
Once you have started the program, you will need to click the scanner button.
The program will close all open browsers!
Once the scan is completed, the you will want to click the Repair button.
At the end of the process you may be asked to reboot your machine.
After you reboot a report will open on your desktop.
Attach the report here in your next reply.



Step 2:

ZHP Diag Scan Click here to download.

Save to your desktop.
Right Click Run as Admin.
Click the Options button.
Click on Check All
Then click close.
Click the Scanner button.
When complete please push the report button.
A notepad will open... attach the report in your next reply.
 
Once I have the log from these two tools, I'll remove any trash I see, and use FRST to set your permissions straight with that file. :)
